There are at least two bands with this name:
(1) A German Rock band which formed in 2002, playing straight-forward guitar rock. They split up again in 2005, having recorded a single EP named "anna".
The members were Tommy Schulte-Wissermann (lead vocals and second guitar), Ulle Wolf (guitar), André Hoffend (drums) and Chris Wolff (bass).
Ulle and Chris are now playing in a band named "Garage Band" (see http://www.garage-band.de/).
