On their first new release in 35 years, revered Brazilian group Os Mutantes update their legendary Tropicalia sound, a politically charged mix of psychedelic rock and indigenous Brazilian music, propelling the band out of the sixties into an uncharted and exotic future. The songs utilize a startling assortment of instrumentation, from austere violins to distorted guitars and something called a crazy flute, lending an underlying theatrical power to the genre-defying music. Os Mutantes previous albums have influenced a host of luminaries from Beck to the Flaming Lips and Kurt Cobain. Features songwriting collaborations with Brazilian legends Tom Ze and Jorge Ben.
