http://www.jamesdomine.com/You might be interested in this American composer whose music is included in downloadable or listenable files in his website. I was attracted to the site because of a mention I saw somewhere of a piano concerto of his. While his music is not exactly barn-burning it is interesting to me, he is a lucky composer who has an orchestra at his disposition, San Fernando Valley S O, to play his compositions, not a very strong orchestra, and perhaps not great music, but something to explore. A caution, some of the audio-files aren't what they say they are, such as Piano Concerto No. 2 files actually call up the files for Piano Concerto No. 1.
