Shinsei Kamattechan are an avant-garde/indie pop band that formed in 2007. They are known for taking simple, playful popsongs, and butchering them with disorientated feedback, shrieked vocals, and an all around chaotic and unnerving sound. Theyare also known for their lyrics, which often consist of death-related themes (their 2010 album, "Minna Shine", translates,literally,to 'Everyone Die'.
