In the 1970s, Os Tincoãs released three of the most revered and unique records of Brazilian music, which crystallized translucid vocal melodies on top of the polyrhythmic percussion patterns of Afro-Brazilian ritualistic music. Now, more than forty years after their last album, Sanzala Cultural has just released Canto Coral Afrobrasileiro, a collection of the trio’s recordings from 1982/83.
