Denmark is a European country that began importing popular American rock and roll music in the 1950s, when that style was conquering audiences across the continent. Danish jazz and dance bands and soloists like Ib Jensen, Otto Brandenburg, Peter Plejl and Ib Glindemann brought the style to Danish listeners. At the end of the decade, the English band The Shadows was a major influence on the first pioneers of the era, The Cliffters and The Rocking Ghosts.
In the early 1960s, British R&B and beat bands inspired Danish counterparts like The Hitmakers, Sir Henry & His Butlers, The Defenders and The Beefeaters, as well as the breakthrough band Steppeulvene, whose 1967 LP Hip revolutionized the field of Danish rock by fusing American folk rock. Young Flowers was the first - and by far the best - rock trio; some of their songs were in Danish language, but several others were adaptions of Walt Whitman lyrics. Jazz bands like Blue Sun, Burnin Red Ivanhoe, Secret Oyster and Maxwells also moved towards rock. At the close of the decade, much of the rock world was incorporating sociopolitical lyrics, along with the rise of the counterculture. Denmark's contribution to this field included Gasolin, Jomfru Ane Band and Røde Mor.
Among middle-aged and older Danes, schlager-resembling Danish folk rock was gaining popularity those days, chiefly artists like John Mogensen, Otto Brandenburg and Kim Larsen.
By the 1980s, however, pop-rock bands like Sneakers, Anne Linnet, Sebastian and Lis Sørensen were popular, alongside punk-influenced Miss B. Haven, TV-2, Sort Sol and Kliché. Most significant was the still popular cowpunk band, D-A-D, who in the late eighties turned into a Ronnie James Dio inspired Heavy Metal band. The following decade saw the rise of pop bands like Michael Learns to Rock, Safri Duo and Aqua, guitar rock bands like Dizzy Mizz Lizzy, Kashmir and Psyched Up Janis.
The current Danish rock scene is dominated by indie influences in bands such as Mike Tramp (formerly singer in White Lion, Freak of Nature and Mabel, The Raveonettes, and Mew. Other popular Danish rock groups include Iceage, Sort Sol (Black sun), VETO, Figurines, Kira and the Kindred Spirits, Carpark North, Saybia, Tim Christensen, The Floor Is Made of Lava and the Danish folk metal band Svartsot. Some of the hard rock bands to come out of Denmark are Volbeat, Red Warszawa, Mercenary, Mercyful Fate (later King Diamond), Artillery, Pretty Maids and Royal Hunt. For alternative rock, Cryoshell started out in affiliation with LEGO, gaining it some market. The most popular of the newer Danish bands is by far the band Nephew, with their unique mix of Danish and English lyrics, and their charismatic lead singer and frontman Simon Kvamm, who has grown to become one of Denmark's biggest stars. Nephew's music is a blend of indie and electro rock.
The annual Roskilde Festival is held in Danish city of Roskilde. The festival is the second-largest in Europe with ticket sales normally running from 70,000 to 100,000. The festival has featured many prominent artists (mainly rock), such as Nirvana, Guns N' Roses, U2, Bob Dylan, Black Sabbath and Green Day, and there has also been an emphasis on world music, alternative genres and Danish music at the festival. In 2000, the festival suffered a terrible accident during a Pearl Jam concert where 9 people were crushed by the wild crowds, making security a primary issue of the following festivals. The festival has since avoided any other incidents of this kind.
