WASHINGTON -- Os Mutantes was once a band record store nerds would to cite to sound cool. Their albums were out-of-print, hard to find and buzzed about. Thanks to re-issues by David Byrne, praise by Beck and Kurt Cobain and a 2006 reunion tour, the Tropicalia band is now known for its sound.
One of the most influential psychedelic music groups of the late 1960s, the Brazilian act is back on the road. In 2009, the band released its first new music in more than 30 years, "Haih or Amortecedor." Continuing to explore new sounds, the group has morphed into an eight-piece world music act.
Now Os Mutantes is headed to D.C. with a performance at The Hamilton on Thursday.
