Over the ages, most of the best-known classical composers were of Germanic origin, and several were French, British and Russian. Patriots will be proud to recall that we can boast a few musical geniuses of solid American stock. On Thursday, Dec. 11, at 7:30 p.m., UNM's University Chorus, Wind Symphony and Symphonic Band joins forces for a performance in Keller Hall of music by American composers Aaron Copeland, Daniel Pinkham, Ralph Vaughn Williams and others. An American Holiday should be a smashingly good show. Tickets are $12, $10 and $7 and are available at the UNM Bookstore (277-5451) or by logging onto www.tickets.com.
