Andrew Hill Trio and Quartet - Shades (1987)

Pianist Andrew Hill's first recording as a leader in six years was particularly notable for co-starring (and challenging) the underrated tenor Clifford Jordan. The quartet set (with bassist Rufus Reid and drummer Ben Riley) has six of Hill's typically challenging and complex inside/outside originals, a perfect outlet for Jordan and the pianist to interact. Stimulating and unusual music that is difficult to classify as anything but "modern jazz."
