Os Mutantes’ second album, recorded while they were still teens, was just as raucous and uninhibited as their debut. Their chops grew bolder and their songwriting prowess was peaking, meaning they could pull off all the melodramatic hairpin turns of Broadway-worthy songs like “Dom Quixote” and “Caminhante Noturno” with exuberance. Psychedelia still informs every song here and the band gives knowing winks to the likes of the Stones (quoting them in the coda to “Mágica”) and the Beatles (“Rita Lee” is a rollicking reimagining of “Don’t Pass Me By”). In hindsight it’s not that audacious, as the upstart Mutantes were every bit the fearless sonic peers of their Western counterparts.
