Chris, A quick place to start is at: http://www.music.indiana.edu/music_resources/composer.html http://www.kanadas.com/music/composers.html http://www.hnh.com/qcomp.htm Without having checked thoroughly, I'm sure most of the 20th century composers listed were born earlier than mid-century, but you might find some leads here. I know there are some deserving names which are not on these sites. Dick Hihn
