Carnival Of The Animals
Introduction Et Rondo Capriccioso
Piano Concerto No. 2
Piano Concerto No. 4
Samson Et Dalila - Bacchanale
Symphony No. 3 'Organ'
Those are my favorites. He had a particularly distinctive style with his strings -- and other than him, I'm not a big fan of violin music.
I hear Piano Concerto No. 5 'Egyptian' is also excellent -- but I don't yet have a recording.
