I agree that the Argerich/Kremer recordings are amazing. I suggest the Ashkenazy/Perlman recordings on the Decca Label I believe. They are pretty good as well. Kremer might take some of the sonatas a bit faster than Perlman. Either way, they are very good. I just performed the Op. 12, No. 1 about a month ago. They are fun to play. Aaron Lofaro
