These lists are extensive, but not comprehensive. There are likely some other more modern, choral-only composers that are not represented either, as well as many experimental composers, and even perhaps a few composers that you believe absolutely should be included but aren't.
For more general information on composers, including biographies and recommended recordings, see the Master Composer Index.
