I light of these comments highlighting KVM failings I've relistened to what I have by him (KVM5, School Days, Freefall).
I can see the R'n'B thing in his solos and granted his improvisations some times seem a little grounded, but the package as a whole is very attractive to listen to.
Live, he and his groups are rivetting and not just because he's surrounded by ace players. Attractive compositions (ok with relatively simple few pretensions beyond their dedications), fine pacing and boundless enthusiam.
I'm still buying KVM.
