Ramsey Lewis - Them Changes (Cadet, 1970)
On this live set, guitarist Phil Upchurch sits in with trio regulars Cleveland Eaton & Morris Jennings. I think this LP and the two that followed -- Back to the Roots (Cadet, 1971) and Upendo Ni Pamoja (Columbia, 1972) -- are all top-shelf Soul Jazz records.
