Speaking of clarinet music, check out Weber's clarinet quintet. It's really glorious. Be careful, though. All his music is very accomplished, but mostof it sounds really soulless to me. Most of the things mentioned already are the thread are happy exceptions. (I just learned the other day that he was Mozart's nephew-in-law, i.e. Constanze's brother's son. The Bachs proved that genius can run in families, but I didn't know it could be transmitted through marriage!)
