Ok, so we all know (or I hope so!

), about his groovy piano concerto. And the instrumentalists get their kicks w/ the much more often performed non solo piano works.
But anyone out there have some expereince and insight on the sonatas? I have been looking and listening and his music and more lately (his sonata in A on imslp for ex), and the more I go into his music, the more I wonder why the solo works are almost unheard of.
I mean, it is understandable how in a sea of Romantic composers, many fall to obscurity, but we do not exactly have nearly a long a list of prolific classical period composers, let along, of the talent exhibited by Hoffmeister.
Is there some stigma against him I'm unaware of? Have you performed any of the sonatas and have favorite in particular? Which one? Why?
Just looking to stir some lively interesting chatter on this and related.
Cheers.
