Katzenjammer is a Norwegian band from Oslo which was formed in 2005. The band members are Anne Marit Bergheim, Marianne Sveen, Solveig Heilo and Turid JÃ¸rgensen. Their music mixes genres such as folk music, pop, rock, country and balkan music. Even though the members are from Norway, their lyrics are in English. The four members switch instruments often and have a stated goal of playing instruments they haven't played before. They play more than 25 different instruments, including some which are quite unusual in a band setting, such as accordion, contrabass balalaika, zither, ukulele and melodica. The band collaborates with Mats RybÃ¸, a fifth "phantom member", who has written the bulk of the band's songs. The band cites many influences including Goran BregoviÄ, Danny Elfman, Django Reinhardt and Knutsen & Ludvigsen. Also, the band states that they are not only inspired by folk but cartoons as well. In 2008 the band was chosen as one of the finalists in NRK's yearly UrÃ¸rt competition for unsigned artists, and got a third place for their song A Bar in Amsterdam. The music video of the song was made by Youtube celebrity Lasse Gjertsen.
