Genesis is the twelfth studio album from the English rock band Genesis, released in October 1983 on Charisma Records. The band decided on its title as each of the album's nine tracks were written as a group. The album cover depicts the shapes from a Shape-O, a children's toy made by Tupperware. Mike Rutherford referred to this album as his favorite Genesis album.
Genesis was a commercial success upon its release. The album reached No. 1 in the UK and No. 9 in the U.S., where it sold over 4 million copies. Five singles were released between 1983 and 1984, with "Mama" being the band's highest-charting single in the UK at number 4. In 2007, Genesis was reissued with a new stereo and 5.1 surround sound mix as part of the band's box set, Genesis 1983–1998.
In October 1982, the band wrapped their two-month tour of North America and Europe in support of their live album, Three Sides Live. They reconvened in May 1983 to start work on their next studio album at The Farm, the band's recording studio in Chiddingfold, Surrey. The album marked the beginning of Hugh Padgham's formal production assistance after engineering the band's previous studio album, Abacab (1981).
The album was developed differently from previous Genesis albums. Prior to this album, each member would bring in their song ideas fully composed. This time, each band member would bring in a fragment of an idea and they would compose the song together through improvisation in the studio. The band did this due to the other commitments taking up their time, as the members by this point had side projects and solo careers. This method allowed them to keep the band unified and the songs fresh.
A "bit" (fragment of music too short to be used as a complete piece) written during Genesis sessions was later developed into the song "A Call to Arms" on Mike + The Mechanics (1985). Collins and Banks were unenthusiastic about the "bit" and had voted against developing it. The album sessions produced no non-album tracks, the only studio sessions since 1974's The Lamb Lies Down on Broadway not to do so. However, a 12-inch single was released with unedited versions of "Mama" and "It's Gonna Get Better," both of which appeared on the album in edited versions. The version of "Mama" on the LP ran 6:46, while the version on the 12" single ran 7:27; the LP version omitted one verse and was faded early. "It's Gonna Get Better" ran 5:00 on the LP and 6:27 on the 12" single; the LP version had a verse and a chorus cut out.
"That's All" was developed from a bit Phil Collins created as a tribute to The Beatles, in particular the drumming style of Ringo Starr, whom he considered one of his drumming influences.
In his retrospective review for AllMusic, Stephen Thomas Erlewine rated the album three and a half stars out of five. He criticised the album for lacking coherency, but found that a majority of the tracks are outstanding, "balancing such sleek, pulsating pop tunes as 'That's All' with a newfound touch for aching ballads." They also praised the band's completely redefining themselves as a pop group. The Kerrang! reviewer determined that for this album Genesis "have traded technical complexity and ingenuity for an altogether more stunning simplicity", making "a Genesis album for people who normally hate Genesis" and "great music for the masses". In 1985 the album received a Grammy Award nomination for Best Rock Performance by a Duo or Group with Vocal while "Second Home by the Sea" was nominated for Best Rock Instrumental Performance.
