I've just discovered the gorgeously played new release of a long awaited new recording of the Frühlingssonate (1944)
for violin & piano by Joseph Marx - not, as expected, from cpo (perhaps they have made a recording of it a long time
ago, but haven't yet managed to get the booklet finished), but from the Austrian label Preiser records.
The soloists are Lidia Baich & Matthias Fletzberger, the sonata is coupled with an equally well played Strauss sonata.

A highly recommended new CD, also available as download from several shops (including Preiser themselves)!

I have this cd. It includes the Marx and the early Strauss Sonata. Both are played magnificently. I deeply recomend this CD!
