I’ve saw Roscoe with Robben at the Jazz Café in Camden. I was upstairs in the restaurant part and he was eating his pre gig meal a couple of tables away. If I hasn’t been with Lady Ez, I may well have had to be the total fanboy and bothered him for a chat (I’m glad I didn’t). Roscoe’s CV is obviously far beyond just jazz tinged blues, but that’s where I discovered him in The Blue Line and then with another of my guitar heroes - Eric Johnson. Roscoe’s instructional video is still one of the best all round bass resources I’ve seen.
Tommy is the king of the shuffle and what impresses me most is his (and Chris Layton’s) ability to be just behind the beat, giving that lazy/dirty feel, even during extended fills, Pride & Joy being a prime example.
