I'm sitting here listening to Ray Brown play electric bass on Quincey Jones' big band version of "Walking in Space" from "Hair." This is the only time I've heard Ray on electric, and it's pretty amazing to hear him on the plank--I assume it's a PBass, but I'm not sure. Still sounds like Ray, though. I've also heard some rare occasions when Ron Carter played electric. Now, I know Ray Brown and Ron Carter didn't give up upright for electric, but, besides Steve Swallow, are there many famous jazz players who went from upright to electric and stayed there? I'm aware of Monk Montgomery playing with Lionel Hampton, and I know Bob Crenshaw plays electric with Sonny Rollins. And, I also have a DVD with Herbie Hancock, Pat Metheny, Jack DeJohnette and Dave Holland where Dave switches between upright and a Peavey 4 string. I'm just looking for some older examples if there are any, to hear the differences in their styles on the two. Oh, I guess there was also that guy Jamerson at Motown. He seemed to have some success on electric after a great career on upright.
