If you’re interested in new American music (mostly contemporary classical music but some other musics as well), there’s a great online resource called “Art of the States.” The Web site, produced in collaboration with WGBH radio, has a large collection of recordings of new music available online, with composers ranging from John Adams to Evan Ziporyn. You won’t hear most of this new music on the radio, nor will you find recordings of it in your local library, so I’m finding this Web site to be a great way to explore the music without having to spend tons of money (which I don’t have) to buy CDs.
