Les Rallizes Dénudés (裸のラリーズ, Hadaka no Rallizes) are an influential, yet reclusive Japanese psychedelic noise band. They were formed in 1967, and the band was known for their ties to avant-garde theater groups (as typified by Shuji Terayama's troupe) and leftist political groups, as well as for their feedback-drenched live shows and use of strobe lights and mirror balls onstage, which earned them comparisons to the Velvet Underground.
