Castelnuovo-Tedesco wrote some very beautiful and atmospheric pieces, somewhat influenced by Debussy, early in his career. Not sure whether sheet music would be easy to get hold of, mind you.
I got hold of one of those Naxos recordings of some of these some years ago, played by one Jordi Maso, and it is a favourite. Castelnuovo-Tedesco actually belongs in a thread of composers who wrote a lot of good stuff but ended up being known for only one composition (in his case, a superlative guitar concerto).
