Piano works, as well as works with cello & piano, due out from Grand Piano. While the back cover does show a couple of tracks from the 1920's, most all the rest of the music appears to be well within the chronological guidelines here. Amazon USA shows a release date of last month, but lists the cd as "currently unavailable" - don't see it yet at any of the other usual sources.

Please remember that there are also stylistic guidelines. For example, although Schoenberg's
Five Orchestral Pieces date from 1909, they're highly dissonant and wouldn't be suitable for discussion here.
I've found our guidelines a little self-contradictory here (by this rule certain late Liszt isn't ok, but by the "grandfathering" rule in the guidelines it is) but I'm aware that's not a Spendiarov thing.
