These performances are amazing, but there are better. For Mendelssohn, my top choices are Heifetz and Milstein. For Beethoven, my top choices are Oistrakh and Menuhin. Nevertheless, his cadenzas do make this an interesting buy. After hearing the usual Mendelssohn cadenza, it is nice to hear something new. The Beethoven cadenza is written very well and I actually prefer it over the often performed Joachim cadenza. Buy this CD if you want great performances, but if you want excellent performances go with my suggested recordings.
