Innovative pop trio from Brazil. Formed in the late 60's by [a260883], [a297267] and [a274890]. They were heavily influenced by British rock bands like the Beatles, and were the first to introduce the psychedelic rock sound to Brazil. Os Mutantes ("The Mutants") are an influential Brazilian psychedelic rock band that were linked with the Tropicália movement of the late 1960s. Although the original line-up (Rita Lee, Arnaldo Baptista and Sérgio Dias; and later with Liminha and Dinho Leme) made the most notorious breakthrough for the group, it has gone through numerous personnel changes throughout its existence. They performed and recorded with many artists of this period, including Caetano Veloso and Gilberto Gil, before Veloso and Gil were arrested and subsequently exiled by the military government of Brazil in early 1969. During this period, Os Mutantes was also threatened by the military government of Brazil of that time.
