Query: Have you heard Chopin Etudes before?

If you want to know how NOT to play Chopin Etudes you must rush and order this CD immediately. I think that anyone who attempts to record anything these days should at least listen to what already exists on the market. Mr. Lifschitz obviously pretends that recordings of Ashkenasy, Argerich, Ginsburg, Pollini, Berezovsky and many others simply do not exist if he permits the release of HIS "version" of Chopin's Op.10. Simply put: when one doesn't have the fingers one should not record these Etudes. They are for the masters, not for students!
