I used to be a big fan of the band Bis . I did a fansite which is no longer updated but still online. It has a comprehensive discography and a gig diary with comments on all 41 gigs I went to. You can find it here .
After the end of Bis in 2003, the former members started a new band called Data Panik in 2005, but sadly they've also split up now.
My current favourite band is the German band Klee , who I have seen live more than a hundred times although I didn't know them until April 2004, when I saw them supporting Cinerama (aka The Wedding Present) in Cologne.
