discovered these works and this composer on IMSLP, and I see all three sonatas are available (I have no idea if the recordings are new or just again available) on Acte Préalable played by Szymon Marciniak (double bass), Joanna Lawrynowicz (piano) (see Nos.1 and 2 (http://www.recordsinternational.com/cd.php?cd=10O060) and No.3 (http://www.recordsinternational.com/cd.php?cd=10O061), each with couplings.) (sonatas pub. 1909, 1911, 1955.)
Acte Prealable announces them as a news
