A rock opera is a work of rock music that presents a storyline told over multiple parts, songs or sections in the manner of opera. A rock opera differs from a conventional rock album, which usually includes songs that are not unified by a common theme or narrative. More recent developments include metal opera and rap opera (sometimes also called hip-hopera). A rock opera tells a coherent story, and may involve songs performed as if sung by separate characters in a drama, as in classical opera.
A rock opera may or may not be presented in a staged performance. In recorded form it can be similar to a concept album (of which it is a subset), though the latter may simply set a mood or maintain a theme.
Origin of the term 
The July 4, 1966 edition of RPM Magazine (published in Toronto) notes that "Bruce Cockburn and Mr [William] Hawkins are working on a Rock Opera, operating on the premise that to write you need only 'something to say'." The Cockburn / Hawkins rock opera seems not to have been completed, though some songs from the project may be among the Cockburn and Hawkins compositions that appeared on 3's a Crowd's 1968 album, Christopher's Movie Matinee.
Alternatively, the term rock opera may have originated at an informal gathering of Pete Townshend, guitarist for The Who, and some friends at some point that same year (i.e., 1966). Townshend is said to have played a comedy tape to his friends called Gratis Amatis, and one of his friends is said to have made the comment that the odd song was a rock opera. Kit Lambert, the Who's co-manager and producer, is then said to have exclaimed "Now there's an idea!". Later that year, The Who released their first attempt at rock opera, the nine-minute six-part track "A Quick One, While He's Away" from their album A Quick One.
Then an Alley, also known as The Beat Opera, was conceived and staged by Tito Schipa, Jr, composer and director, son of the tenor Tito Schipa, at the Piper Club in Rome, Italy, in May 1967. While Then an Alley, an adaptation of 18 Bob Dylan songs made to fit into a scenic background, made a moderate splash in its country of origin, it went completely unnoticed elsewhere in the world. Schipa Jr. later went on to write and stage the work Orfeo 9 at the Sistina Theater in Rome. It became the first ever staged original Italian rock opera when it debuted in January 1970. Orfeo 9 became a double album and a film under the musical direction of future Academy Award winner Bill Conti.
Early examples 
- The Story of Simon Simopath: In October 1967 the British group Nirvana (not to be confused with the later American band of the same name) released The Story of Simon Simopath, what might be the first entire album by a rock band to comprise a single story, and thus the very first rock opera in history. In November of that same year the Montreal group Influence traveled to New York to record what they called a 'mini-opera', "Mad Birds Of Prey", and other songs for their only album.
- The Crazy World of Arthur Brown: In August 1968, The Family Tree released Miss Butters, the birth-to-death story of a schoolteacher. September 1968 saw release of the Crazy World of Arthur Brown's eponymous first album, produced by Kit Lambert, which featured a side-long mini-opera reflecting on the horrors of Hell. The Pretty Things released S.F. Sorrow in December 1968, which told the story of protagonist Sebastian F. Sorrow's life from the cradle to the grave and from joy to misery.
- Tommy: In April 1969 Pete Townshend and The Who released Tommy, the first of The Who's two full-scale rock opera and the first musical work explicitly billed as a rock opera. [In some older publications it is called Tommy (1914–1984).] Produced by Lambert, the album's content was largely composed by Townshend, with two tracks contributed by bassist John Entwistle and one attributed to drummer Keith Moon, although actually written by Townshend. Tommy remains one of the most famous rock operas, with concert, film, ballet, and theatrical productions mounted over the course of four decades. The Who would later release another rock opera, Quadrophenia (1973), also made into a film and a stage musical.
- Arthur (Or the Decline and Fall of the British Empire): In October 1969, The Kinks released Arthur (Or the Decline and Fall of the British Empire) their own attempt at a rock opera, released just after Tommy, with great commercial and critical success. It deals with a British man, Arthur, reflecting on his life after his son announces a sudden move to Australia. In the first half of the 1970s the Kinks released a series of rock operas: Preservation: Act 1 (1973), Preservation: Act 2 (1974), Soap Opera (1975) and Schoolboys in Disgrace (1976). All these albums were followed by a series of stage productions, in which the band members, and additional personnel, acted as musical and theatre performers.
Townshend's Tommy influenced many, including composer Andrew Lloyd Webber who, with lyricist Tim Rice, composed Jesus Christ Superstar which was first recorded and released as a concept album in 1970. The money made from album sales was used to fund the subsequent stage production in late 1971, which had been Lloyd Webber and Rice's original vision. Jesus Christ Superstar was explicitly billed as a "rock opera" and though it first appeared in recorded form, it became far more famous as a Broadway musical, leading it to be called a "rock musical", blurring the distinction between the two terms. Another collaboration of Rice and Lloyd Webber was Evita, which is supposedly considered a rock opera, along with Broadway musical styled songs. The show (like Jesus Christ Superstar) is told entirely in song and, at first, producers[who?] thought that it would be a flop on the Broadway stage. However, it was nominated for five Tony Awards, including "Best Musical".
In 1972, David Bowie released his rock opera The Rise and Fall of Ziggy Stardust and the Spiders from Mars, the story of a rock star who is told by aliens to write music in the years preceding the end of the world. The next year, The Who released their second full rock opera Quadrophenia. It is about a mid-1960s teen living with a personality disorder. Also in 1973, Lou Reed released Berlin, a tragic rock opera about a doomed couple, which addresses themes of drug use, depression and suicide. In 1974, Genesis released the rock opera The Lamb Lies Down on Broadway, a surreal story about a young man on a journey of self-discovery.
In 1978, composer and record producer Jeff Wayne released a musical version of H. G. Wells's Victorian apocalyptic science fiction novel The War of the Worlds, in which a number of high profile singers and musicians featured such as David Essex, who worked with Wayne as a producer on his solo career, Moody Blues' singer Justin Hayward, Thin Lizzy vocalist/bassist Phil Lynott, and Julie Covington who had previously sung in Evita. The plot was narrated throughout by an unnamed journalist protagonist played by Richard Burton.
In 1979, Pink Floyd's rock opera The Wall, written primarily by Roger Waters, was released. The Wall has been staged as an elaborate theatre performance by Pink Floyd in 1980 and 1981, by Waters in 1990 in Berlin, and in 2010, 2011, and 2012 by Waters as a worldwide solo tour. It is one of the highest rated and most well known rock operas. The plot was also used for the feature film Pink Floyd The Wall, and Waters is currently adapting the story for a Broadway production. The Wall is one of the best selling rock operas to date. During his subsequent solo career, Waters went on to write two rock operas, The Pros and Cons of Hitch Hiking (1984) and Radio K.A.O.S. (1987).
1979 also saw the release of Frank Zappa's Joe's Garage, a three act rock opera about the life of a young musician named Joe, set in a dystopian future where music was made illegal, inspired in part by the Iranian Revolution, which outlawed public musical expression. The album also takes jabs at Scientology.
Weezer frontman Rivers Cuomo had planned to produce an album called Songs from the Black Hole, which was to be a rock opera about a group of people pursuing an adventure in outer space to rescue an unidentified person or object. After the project was then abandoned in 1995, the band replaced it with their album, Pinkerton. Most of the demo recordings are available, legally or as bootlegs, though four remain unreleased.
In 1995 Arjen Anthony Lucassen started his Ayreon project with its first rock opera The Final Experiment, followed by Into the Electric Castle (1998), The Universal Migrator Part 1 & Part 2 (2000), The Human Equation (2004) and 01011001 (2008), which though all self-contained overall formed a continuing bigger story.
Edguy singer and main songwriter Tobias Sammet has written three separate rock operas under the project name Avantasia. The first, The Metal Opera, was released as two albums. The Metal Opera (2001) and The Metal Opera Part II (2002). The second rock opera is known as The Wicked Trilogy and spans three albums The Scarecrow (2008), The Wicked Symphony (2010) and Angel of Babylon (2010). The third installment begins with The Mystery of Time (2013) and will be concluded with the release of another album. All three operas feature many well known rock musicians.
Some heavy metal bands have released albums inspired by rock opera, often in a progressive metal framework. In some cases they have overlapped considerably with the format of metal concept albums. Queensrÿche's fourth album Operation: Mindcrime expanded the genre from their previous three rock opera by bridging rock opera with real opera and a stage production complete with the story playing on jumbotrons in live versions and DVD releases. Albums by Opeth (My Arms, Your Hearse), W.A.S.P. (The Crimson Idol, The Neon God: Part 1 - The Rise, The Neon God, Pt. 2: The Demise), Dream Theater (Scenes From a Memory), Kamelot (Epica, The Black Halo), Blind Guardian, Dimmu Borgir, Pain of Salvation, Protest the Hero (Kezia) and Epidemia are a few examples of metal opera albums. The Italian power metal band Rhapsody of Fire (formerly "Rhapsody") released several complementary albums that each continued a single mega-"DragonRock" opera. King Diamond has almost exclusively released metal opera albums, with only two albums containing stand alone tracks (though even these albums have several related tracks each).
The American heavy metal band Savatage released three rock operas, Streets: A Rock Opera (1991), Dead Winter Dead (1995) and The Wake of Magellan (1998), before the same composers continued the release of a series of rock operas under the banner of American progressive metal band Trans-Siberian Orchestra, including Christmas Eve and Other Stories (1996), The Christmas Attic (1998), Beethoven's Last Night (2001), The Lost Christmas Eve (2004) and the two-disc Night Castle (2009).
The composer Andy DiGelsomina calls his Lyraka project "Wagnerian Opera Metal", due to the influence of Richard Wagner's opera Der Ring Des Nibelungen. The project's first release, Lyraka Volume 1, received much critical acclaim, with Martin Popoff referring to DiGelsomina as a "great songwriter", and the opera itself as "the next Led Zeppelin". The second volume of the opera is being recorded and is slated for release December 2012.
Punk rock opera is a term coined by the punk band Green Day to describe their 2004 album, American Idiot, which was written about a teenage boy who runs away from home to find himself and how his life is before and after.
