Os Mutantes have announced a tour of North America in support of their startling new album “Haih or Amortecedor.” Seeing the legendary “Tropica” band live is something Kurt Cobain could have only wished for when he pleaded (unsuccessfully) for them to reunite and tour with Nirvana. Now Brazils' beloved Mutantes, long regarded as one of the most influential and innovative bands in pop music, have returned with both an ambitious new album and a series of highly anticipated performances. Revered by musical luminaries including Beck, Devendra Banhart, David Byrne, Of Montr, The Flaming Lips and Cobain, the reunited Mutantes offer something far more intriguing than mere psychedelic nostalgia. While the ingenious genre blending Tropica spirit remains intact on “Haih or Amortecedor”, it's clear the Mutantes are not looking to the past, but ahead into further uncharted musical terrain.
