"die ärzte" is, together with "Die toten Hosen", the most successful german band, that roots in punk music. They were formed in Berlin in 1982 and have, since then produced over 20 albums. They were struggling with each other a long time, so 1988 they decided to break up, until 1993 they finally released the album "13". Since then they have developed their style further and further, and have gotten pretty crazy, but I like them a lot

They are kinda funky, btw. They have also done a MTV-Unplugged-Session, called "Rock 'n Roll Realschule".
Vokuhila Superstar

Deine Schuld(Your Fault)
oh yeah, and something unplugged would be good:
Schrei nach Liebe (Scream for Love)
