Mozart's Divertimento K.334 is one of his very best works in the divertimento genre--complex, almost symphonic in scale, with fascinating and beautiful ideas. The tempos in this recording are well-chosen, all the repeats are included (important) and the recording quality is excellent. Nothing is glossed over here, and great attention is given to subtleties of detail and phrasing while still retaining a graceful, musical line. This is simply first rate in every way.
There are other recordings you can consider. Another chamber version, by Werner Hink and I Solisti Di Perugia on the Camerata label, is good. The Gaudier ensemble on Hyperion also makes a nice alternative, with a performance that sounds slightly more freewheeling and rollicking, in the spirit of a "divertimento." If you like your Mozart on the slick and syrupy side, then Karajan and Raymond Leppard have made orchestral versions that you will like. For those who can handle historical mono recordings, Fritz Reiner's late 1950s Chicago recording exemplifies the ideal--poised, alert, and beautifully phrased--but the mono sound seems rather dry.
