I think for me it was a $1 (the whole store was $1 cutout LP's) Cobblestone LP of Jimmy Heath's "The Gap Sealer". That one opened up new worlds for me.
Go to his website and run through the links for each month. Much quicker than going back through these posts. I'm also not a big fan of piano/sax duets, own very few that are standalone (have some in collections).
There was no internet and no Ruppli discography, so the prime sources of discovering what was in the BN catalog were old Schwann catalogs and the inner sleeves for other old BN albums, which were used to advertise other albums. So you could be at Woolworth's or something in the dollar bin, and find a BN album that not only did you not own, but that you didn't even know existed.

My very favorite Tolliver album. Awesome. 1201 is fine, though absolutely no frills. The album was originally on Freedom records, so any other label is a lease (at best). I first owned it as a reissue on the Arista-Freedom label in the mid-70's, then got the Black Lion CD in the early 90's.
139 for me, almost all on CD. But of course, my collection is heavily weighted to the 50's, 60's, and 70's. Do this for the last 40 years, or for the 20's-40's, and my #'s would be much less.
Saw him at the Foxhole Cafe in the mid-70's. Definitely Beaver Harris, and I believe Dave Burrell and Cameron Brown. They tore the roof off the building, especially on "African Drums".
There was already a mystique here in my world (Philly) by the time I started with jazz in the early 70's. I knew to grab any 50's/60's Blue Note out of a cutout or cheap used bin, if I knew the artist or not. I had some good guys in record stores (not just Third Street Jazz, but also Franklin Records in Plymouth Meeting Mall) who trained me well.
