I've just discovered that Naxos' music download site, ClassicsOnline.com, has my chamber piece available. There are a few other sites that have the CD available, including iTunes, but you have to buy the whole CD to get my piece. On the Naxos site you can buy just my track, for $2.39.
Click here to go to the page for New American Masters Vol. 3 on the ClassicsOnline site if you're interested in buying the track. There's a 30-second preview there as well.
(The CD is listed on iTunes, but since my track is just a hair over 10 mins you have to buy the whole CD from iTunes. However, on iTunes the preview clip is 90 seconds long.)
