Respighi Piano Sonata P 016/etc.

[Alan Howe]

Sounds like rather a lovely recording:

There's already a pretty decent live recording of the Sonata by Antonio Pompa-Baldi on Centaur, of course, also coupled with the Six Pieces but with the bonus of Respighi's Piano Concerto. I must look it out, haven't played it for ages.

Looks like this has been digital for a while. Tidal lists last April as the release date.

There's also a recording by Giovanna Gatto on Volume 1 of the complete piano music on Toccata Classics.
