This is a real treasure to have if you enjoy his film music. Rozsa was one composer who enjoyed success in concert as well as soundtrack material.

Hrm. I have a cassette tape of Rozsa's string trio in D op.1 and piano quintet in F minor op.2. The rhapsody op.3 for cello and piano or orchestra of 1929 (also recorded in its cello/piano form a couple of times) - just out of curiosity do you know if the orchestration is Rozsa's? Hrm... never mind, the description in the worklist at miklosrozsa.info (http://miklosrozsa.info) gives orchestra first.
I believe his chief orchestrator was a fellow Hungarian Eugene Zador.
