Callejon is a German metalcore band founded in Dusseldorf in 2002. Most of their lyrics are in the German language. Their latest albums are Blitzkreuz from 2012 and Mann spricht Deutsch (covers only) from 2013.
Bandmembers are Bastian Sobtzick (vocals), Bernhard Horn and Christoph Koterzina (guitars), Thorsten Becker (bass) and Max Kotzmann (drums).
I saw them when they were support for Bullet For My Valentine.
