I don't know much about DOPPELGÄNGER or DOPPELGANGER as most people from the states, I guess cause of lacking the Ä, spell them. they are from California and members played in ROSENBOMBS and PUNCH and their demo comes has 17 songs that have a playing time of around 10 minutes! I found this one on the web so sorry for no cover, etc. but I don't have all that! I think they are not as awesome as PUNCH or ROSENBOMBS but that does not hinder them to be a really great band!
