In 1968, the Brazilian band Os Mutantes released its first album. The band was part of the tropicalia movement, fusing Brazilian music, psychedelic rock, political commentary and more. They broke up in 1978, but their legend continued to grow, and their reunion 10 years ago was greeted with international acclaim. Os Mutantes, or "The Mutants" in Portuguese, continue to make mutant, genre-hopping music, like this song called "Once Upon A Flight." The influential Brazilian band Os Mutantes play at Webster Hall tonight.
