I ran some searches and couldn't find anything about him on here. I have a Chico Hamilton album called "Man from two worlds" that Al Stinson is on, and I feel like he gets slept on a lot. In my opinion he was up on the same level as a Scott LaFaro or Gary Peacock, and had a HUGE sound, big groove, and played some very interesting ideas. I've only heard him on this one recording, but I know there are some other Chico Hamilton albums he's on, and I believe there's a Clare Fischer trio album he's on (along with Gary Peacock on some tracks). Doug Weiss told me a few years back about him, and told me about a particular (out of print) Bobby Hutcherson album called "Oblique" that Stinson plays on. Anyone have any more info about him?
