Carol Kaye and Motown Unreleased
A balanced article by Brian Wright from 2019 indicates that much of Kaye's known West Coast bass work remains unreleased. He also provides a detailed record of every Motown Los Angeles Musician's Union contract that lists Carol Kaye as a performer.
Without going over the various arguments [[Jamerson v Kaye), there does appear to be a sizeable number of Kaye tracks listed that may still remain unreleased. Would be good to get an opinion from those in the know as to the possibility that any of the unreleased tracks may see the light of day soon [[some have obviously already been made available).
