Legendary Brazilian psych-rock/tropicalismo group Os Mutantes has inspired everyone from David Byrne to Beck to Kurt Cobain. From 1966 to 1978, the group released six studio records chock-full of samba beats, bossa nova rhythms, and psychedelic vibes. They reuinited in 2006, and have been touring sporadically ever since, and their most recent tour brings them to the World Cafe Live tomorrow night. We’d like you to be there.
