Unbeknownst to most people, Motown had a jazz division in the early 1960s. Shown below is the entire output from the "Workshop Jazz" label.
There were other releases planned, recorded, catalogue numbers allotted, and even cover slicks made that show up on inner sleeves and other
advertisements, but the records were never released. The most famous unreleased album is what would have been the first Four Tops LP with
them singing standards. Apparently Berry Gordy nixed it at the last minute. It has since come out on CD and is titled "Breaking Through."
