A lot of this CD is very impressive- Vengerov clearly has his technique under control, and the Paganini is very well-executed, making it sound easy.
I feel that he's pretty far off the mark with the Messiaen, though. He must not have spent very much time learning this piece, since both the Theme (of the "Theme et variations) and the final section of the piece are played at exactly twice the printed tempo! This completely changes the character of the piece to something that's very different from the meditative quality that the correct tempo markings imply. There are also a few wrong notes- small details, but it does make a difference, considering the emphasis Messiaen placed on harmony. There's a very good Naxos recording of this piece (with the Amici ensemble, Scott St. John, violin) that's worth hearing.
