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 Jørgensen. Their music mixes genres such as folk music, pop, rock, country and Balkan music. The four members switch instruments often and have a stated goal of playing instruments they have not played before.They play more than 25 different instruments including the accordion, contrabass balalaika, zither, ukulele and melodica. The band collaborates with Mats Rybø, a fifth “phantom member”, who has written the bulk of the band’s songs. Another personal highlight for me on the Southside Festival 2012 in germany , if you ever get the chance to see them live , please don´t hesitate to go there , really a highlight. Here is their song “I will dance ” Katzenjammer is german and means in english “cat sorrow” a synonym for bad , worthless music haha
