Whoops, wrong subforum...
David Frühwirth, mentioned recently in connection with the Weigl violin concerto, mentions on his website (http://www.davidviolin.com/2012/wordpress/?page_id=759) starting his new association with Crystal Classics with a CD with world premiere recordings (claimed and probably) of several violin and piano works by Nikolai Rakov, including the first 2 violin sonatas and several violin sonatinas (out since March apparently.)
(His website lists some interesting recordings I hadn't seen before including one with Kornauth's violin sonata. Nice!)
