I can think of some excellent sides on US RCA-Victor:
Bill Dixon - Intents and Purposes
Sonny Rollins - Our Man in Jazz
Sonny Meets Hawk
Joe Daley - At Newport '63
Gary Burton - Duster
Jeanne Lee & Ran Blake - The Newest Sound Around
George Russell - Jazz Workshop
Not to mention some excellent discs on European and Japanese RCA imprints by Mal Waldron, Steve Lacy, Lee Konitz, Charlie Mariano, Keith Tippett, Chris McGregor, Ray Russell, Tony Oxley...
