This tune is great!!!Hermeto Pascoal is just great.
The first time I heard of him was during the 70s, when his record Slaves Mass came out. Here's the first tune from that record, in 7/8, with Chester Thompson on drums and Alfonso Johnson on bass.
Also I attended his Montreux concert, in 1978 probably. Then one night in the mid-80s, I saw him jam in a club in Paris, and he was amazing.
