Brazilian trailblazers Os Mutantes’ psychedelic Tropicália journey begins with this self-titled debut, originally released in 1968. Its been an underground favourite around the globe ever since. Centred on the vocals of Rita Lee, Sergio Dias and Arnaldo Baptista, the album weaves together soul, bossa nova and rock influences with uncanny aplomb. There’s a playful sense of experimentation throughout Os Mutantes: the opener, “Panis Et Circencis”, grinds to a halt at one point, as if someone’s physically stopping a vinyl record mid-revolution. But it also includes accessible psych-pop tunes like fuzztone classic “A Minha Menina” and the subversive Caetano Veloso-penned ballad “Baby”.
