Wasn't Renaud more a catalyst than a great pianist, actually? I mean, having all those JiP and Vogue discs he pops up everywhere, and I never really thought his playing was that great. There's nothing wrong with it, for sure, but sometimes I'd with for Solal or Urtreger or Peiffer instead...
If you're interested in all star affairs, there's also that date on one of the first of the "Birdlanders" OJCs, feat. Renaud with Kai & Jay, Cohn, Bags, Percy Heath, a.o.
