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.
