Well I say 'hurrah' for Edu. Here's a list of works I feel all the better for knowing:
Introduction and Allegro for Strings
Serenade for Strings
Nursery Suite
Symphony No. 1
Symphony No. 2
Cello Concerto
Sospiri (Barbirolli's recording especially wonderful)
Dream Children
'Intermezzo' (touching, restrained piece for violin solo and orchestra, composed to be part of Crown of India Suite, which is probably why it's a much deeper work than the movements in which it is embedded).
Many other pieces I enjoy listening to from time to time. Elgar's an undying favourite for me.
