Roots of Os Mutantes

Legião Urbana was a Brazilian rock band formed in 1982 in Brasília, Distrito Federal. The band primarily consisted of Renato Russo, Dado Villa-Lobos (guitar), Renato Rocha (bass), and Marcelo Bonfá. Rocha left the band in 1989, and the band continued as a trio until their disbandment, with Russo becoming the band's de facto bassist after Rocha's departure. Following Rocha's death in 2015, Villa-Lobos and Bonfá are the last surviving members of the band's principal lineup.

Tecnicolor would have been the fourth album by the Brazilian band Os Mutantes. The album was intended to be their introduction in the English-speaking world and included English versions of songs from the albums Os Mutantes and A Divina Comédia ou Ando Meio Desligado, re-recordings in Portuguese and French, and several new songs. It was recorded in Paris, in 1970, but released only 30 years later.
