Uniao Black were a 13 strong groove machine that came storming out of Rio with a self-titled album in 1977 determined to take over the world. They didn't, but they should've.
"Geracao Black" - Uniao Black
"Melo Do Bobo" - Uniao Black
The gang disbanded the year after the album came out but some of the original members got back together in 2004 (now with a Banda in front of their name). They released a second album in 2006 before retreating again.
I thought they might have done some videos for the second album but I can't find any. So instead we bring you their local rivals Banda Black Rio from 1981. Never mind the video quality, dig the sound.
