I had a slew of those Everests as a teenager, jazz and blues. The Dolphy Music Matador session was half of one lp. The Mingus session with Thrice Upon a Theme, etc. They had Bird's Royal Roost broadcasts as well as the Birdland one mentioned above. I had that Haig album too (and used to see him & Jimmy Raney at a bar called Gregory's). The Cannonball and Trane session was issued on that label too, which is one of the most weird, because wasn't it originally on Mercury?
The Rollins session is pretty good. First recording of Sonnymoon, right?
