Gilberto Gil

As twisted and psychedelic as any of the music in the post-Sgt. Pepper world, these artists mix sound experimentation with a lush sense of melody. Some incredibly vibrant music is the result. Gilberto Gil's "Bat Macamba," Gal Costa's "Nao Identificado," Caetano Veloso's "Baby," and Os Mutantes' "Panis Et Circenses" are all positively life-changing.
