I am beginning to get the feeling that some kind of translation interface needs to be added here.
"cutting edge" - I still have no clue as to what it is you really want to listen to. If the only two bassists that were on that record you heard were Ray Brown and Christian McBride, well I wouldn't call EITHER player "innovative" or "cutting edge". Ray is very firmly coming out of the Chambers>Pettiford>Blanton lineage and Christian has got that heritage mixed with a contemporary funk sensibility. So if what you are REALLY asking is where you can hear some more stuff that's going to be like the stuff you heard, check out:
Michael Moore
John Clayton
Lynn Seaton
Dave Young (although I don't dig his bow sound)
but also check out Paul Chambers and Jimmy Blanton, because that's the "wellspring" of that conception.
If what you want is cutting edge, check out William Parker, Sirone, David Izenzon, Peter Kowald, cats like that.
