The appassionato is a reworking of the piece into a single movement. The original sonata is more coherent and preferable, despite the fact that only the first movement has much meat. Although it has some beauty to it, it has a very clunky opening. It's certainly juvenalia. Interestingly enough, the apparently earlier Sonata Fantasy is a more polished mature-sounding piece, although it is also comparatively simplistic in terms of Scriabin's mature works.
Glemser, Coombs, Szidon, and Ponti are available on CD. Glemser and Coombs are better than Szidon and Ponti for this piece, with a nod to Glemser who does his best to create interest rather than merely go through the motions.
