Listening to a Claude Thornhill anthology that provides a nice overview of his prime years, from the mid-1930s into the early 1950s. Caveat that it's a 2015 Acrobat CD-R release, but it was seven bucks new at my local record store:
Praise always to the late Alastair Robertson for having shepherded eight CDs of Thornhill material into being through his invaluable Hep series, though I still wish Mosaic had been able to usher something of its own into existence--but I imagine the market for a Thornhill set might have been thin even 20-30 years ago. The individual Hep volumes remain my go-to Thornhill CDs, but this is perfect for an anthology mood (and about half of the first disc consists of sideman and early leader dates that took place before 1940, when the Hep series begins chronologically with the Snowfall CD).
