Black Unity – Pharaoh Sanders

LP Vinyl.

From Wikipedia:

Black Unity is a composition and album by jazz saxophonist Pharoah Sanders, recorded and released in late 1971. The whole album consists of a single thirty-seven-minute track, which was described by critic Joe S. Harrington as “an exercise in sustained harmonic groove that cannot be beaten”^[1] when he listed it at #38 on his Top 100 Albums. The compact disc reissue of 1997 unites the two parts as a single track, timed at 37:21.
