Few bands can claim to make music so dangerous, its members become enemies of the state. Brazil's Os Mutantes is one of those lucky few.
Formed in the mid-1960s--as Brazil was in the clutches of military rule--Os Mutantes' combination of American psychedelic pop and traditional Brazilian music was targeted by the government, resulting in frequent raids during live concerts and attempts to censor the band's lyrics.
Bands like Talking Heads, The Flaming Lips and Of Montreal have cited Os Mutantes as a major influence. Kurt Cobain allegedly tried to track down the band to get it to re-form while Nirvana was touring Brazil. Beck said it was all he would listen to for years.
Os Mutantes reunited in 2006 to record its first new album in three decades and hasn't stopped touring since.
