Pacific Jazz released a considerable number of 7" 33rpm records, meant for DJs, or radio play, or juke boxes?
The single Harold Land track with Jackie Davis seems to be a one shot affair. I cannot find any other tracks with about the same personnel or whatever. The two compilations, btw, have different edits of that same track - the one on the LP I just bought unfortunately is the shortened version.
And yes, it would take someone like James Harrod to sort out all the different versions of tracks Richard Bock used on his compilations, and list the CD reissues they were added to as bonus tracks. Fresh Sound thought about some, Cuscuna used some, but both overlooked a few.
