Greetings---I have just heard the 3rd Sonata of Perichetti---enjoyed it
. Are there good recordings of the Sonatas/piano works. I have used his "little Piano Book" with my students. Are there other Sonatas by him i should consider learning. Thanks!

Off topic, but thanks for kicking my brain in gear, as I've been confussing Tchrepnin (and possibly others) with Persecutti (sp?

) - meaning that between my pre-teen years and mid-30's I kept returning to the same Hungarian piano teacher, who suggested Prescetitti (sp?) more than thrice, yet after just a short intro I was drawn back toward Bartok.
Please understand that I'm not making fun of the composer you are asking about (I just don't know how to spell the name), and have, for many years wondered what his best piano works were. Hopefully they were more purely musical than the unfortunate examples (yet certainly well conceived) that I ever ran into when I was a lad.
So if you find something remarkable, please pass it on...
