For this disc (https://www.amazon.com/Galax-Whelden-Carl-Friedrich-Abel/dp/B000000R3J) there are two composers, Roy Whelden & Carl Friedrich Abel, and two performers, Roy Whelden and American Baroque. Ordinarily on the release/release group artist I would put the composers followed by semi-colon followed by the performers. Do I list Roy Whelden twice, once in each rôle?
