The first thing one notices about this disc is the attractive sound, rounded yet detailed; the second is that the playing of the orchestra is stylish; last but not least, the soloist's first entry tells us that he, too, is a fine player. Rainer Kussmaul's name was unknown to me, but a note on the jewel-case says that he is about to become leader of the Berlin Philharmonic Orchestra. He produces a lovely sound on what sounds like an excellent instrument, and phrases gracefully: altogether this is most enjoyable Haydn playing.
