Through the magic of crate-digging, Diplo turned on thousands of hipsters onto Brazilian Tropicalia of yesterday and today.

Through the magic of crate-digging, Diplo turned on thousands of hipsters onto Brazilian Tropicalia of yesterday and today. But some of this country's leading cool cats, from Byrne to Beck to Cobain, have been hyping Os Mutantes for decades, and for good reason. Blending psychedelic rock with the equatorial flair that characterized Brazil's folk tradition, they built a rich and lengthy legacy. The band lay dormant from 1978 until 2006, but they're back as a fully functional unit touring behind a new album, Haih or Amortecedor.
