Brahms' late, melancholy Double Concerto gets top billing here, and the brothers Capucon are very good in it. But for me the winner on this CD is the Clarinet Quintet. Its free-form rhapsody suits the Capucon Quartet and Paul Meyer, the bright, elegant clarinetist. The pitfall in this work is that it tempts the players to swoon and over-emote. When that happens, you feel lost in thick Romantic pea soup. I had more or less given up on the work, but this reading restores my faith. It's crisp, forward-moving, and not overly earnest. The sonics from EMI/Virgin are very clear, if a bit edgy at top volume. Definitely a five-star performance.
As for the Double Concerto, I think the performance fights against itself. As you can tell from the first entry of the cello, the Capucon brothers are out to maximize emotion and to pull the ad lib melodic line as far as it can go. But Myung-Whun Chung is rather reticent in his conducting, and the Mahler Youth Orchestra's lighter texture isn't in keeping with the two soloists, who play as if they are on a very big stage. In other respects, however, this is certainly a fine reading.
In all, the Doublte Concerto can't compete with the best in the field, but the Capucons' sweet, light-handed Clarinet Qt. can.
