Os Mutantes showed an interest in following international music trends from the very beginning of their career, when they moved away from the traditional sounds of their native Brazil in favor of psychedelia. Even its own name gives us some clues about the ever-transforming will of the band. The continuous changes characterized the group’s history until its dissolution in 1978 and, as part of that evolution, they embraced progressive rock in their final albums. Tudo foi feito pelo sol was released in 1974, when Rita Lee was already focused on her solo career and Arnaldo Baptista had also left the group due to internal and personal problems. The only original member left, Sérgio Dias, along with bassist Liminha, who had joined the band a few years earlier but left before recording this album, were responsible for composing most of these songs. Despite the obvious differences from the original sound of Os Mutantes, this record will not disappoint the fans of the band. ‘Deixe entrar um pouco d’água no quintal’, ‘Cidadão da terra’ or ‘Tudo foi feito pelo sol’ clearly leave aside any reference to Tropicalismo to embrace instead the hardest sounds and progressive style of groups like Deep Purple or even Iron Butterfly. The keyboardist Túlio Mourão stars in some of the most intense moments of the album, along with the energetic and fierce guitar of Sérgio Dias, who was the band’s leader at the time. An example of their virtuosity is ‘Pitágoras’, written by Mourão, where piano and guitar take us into a progressive and almost psychedelic journey with music references as diverse as jazz and flamenco. Without any doubt, this is one of the strongest songs of the entire LP, hence it has still been part of the band’s repertoire in recent tours.
