If you're looking for some more traditional music to listen to, you can't go wrong with the Mozart Concerti. The Mozart Clarinet Concerto has been on every orchestral audition I have ever taken and with good reason. As a player you have to make it sound easy, it's not. The piece is very transparent and has a lot of pit falls.
Sabine Meyer is one of my clarinet heros (I have several) and if you haven't listened to her before this is an excellent place to start.
This copy I brought home from the Saskatoon Public Library but I'm sure you can find a copy at your local library as well.
