I could be described as a fan of Leroy's. I got pretty heavy into him in my last year of college. For those who aren't familiar, Leroy's style was to walk for his solos as well as for accompaniment. I just loved his sound and feel. There's a bunch of west coast records that would have sounded a lot lamer if he hadn't come in and lifted them up.
One thing that I noticed when I started learning his parts off records was that he would play basically almost the same bass line over and over, chorus after chorus. Then his solo would come, the band would drop out and Leroy would walk, expanding on his original line with rakes and drops and all that. At first I thought, "What's this? Is he saving his best stuff for his own solos?" I was actually a little put off. But I talked to an older bassist who I respected about it. I said "Man he plays the same line over and over again.." His reply: "Yeah but it's a GREAT line, right?" It was true.
It kind of reminds me of a great story my wife told me. She went to the Mt Fuji jazz festival some years ago where she saw Art Blakey's band with a young Peter Washington. At the end, there was a sort of all-star jam session, with Herbie Hancock on piano and maybe Tony Williams on drums, I can't remember just now. Anyway, they played Just One of Those things, and Herbie and the drummer and horn players started playing all kinds of crazy stuff. All through the storm, Peter just played the tune. He didn't try to follow all the crazy s*** going on around him, he just closed his eyes and laid it down. My wife said because of the shaved head, and because he didn't let anything affect him, and just made himself the center in a certain way, he looked like a Buddhist monk up there playing bass, the sound of one hand clapping itself. In some ways, I think Leroy was like that too. He wasn't all trying to be clever and "interactive," just getting deep, deep into the groove.
If one of the things I've learned from Ron Carter is that you can find endless new ideas to play basslines on even the simplest chord progressions, then one of the things I've learned from Leroy Vinnegar is that even a single line repeated many times can be just as great, if it's played with depth and conviction.
As to records, his leader records "Leroy Walks" and "Leroy Walks Again" are great, real favourites of mine. The other famous ones make good starting points: Shelley Manne's "My Fair Lady," where Leroy achieves the near impossible task of making Andre Previn almost sound like he's swinging

and Les McCann's "Swiss Movement"
Leroy. Yeah.
