It would be most likely too harsh stating that George Cables ruins a performance/recording. Nevertheless, as me being a dedicated Art Pepper follower, comparable impressions come to my mind like expressed in the openening post. George Cables was Art`s pianist for a number of recordings and tours and so for instance on his much heralded "Live at the Village Vanguard" records for Contemporary. I never felt comfortable with this and credited it inter alias also to Elvin Jones (running his own thing ?)......more than a year ago Laurie Pepper made available a tape showcasing Art Pepper @The Village Vanguard a couple of weeks before the Contemporary recordings

with a rhythm section consisting of Onaje Allen Gumbs (p) Gene Perla (b) and Joe LaBarbara (dr). Gumb`s playing is sensitive, imaginative but challenging for Pepper at the same time and the Perla/LaBarbara tandem grant an excellent backbone. For my taste it`s a pity, that the Contemporary recording didn`t feature these musicians at work.....
Cables was Pepper`s pianist on most of the Galaxy recordings, but alternatively Pepper played with his love/hate relationship Milcho Leviev and IMO the recordings with the later ("Live at Ronnie Scott`s"...) are reflecting the tension beetween both artists, bringing the best out of them...an impression i don`t get from Pepper`s Galaxy recordings.....
So probably this is also about George Cables...just my 5 cent worth...
