21st Century (2012). Premiered at the 2012 International Trombone Festival (ITF), Paris France. For 8 or 12 trombones with optional organ. Set as a pair (or trio) of equal TTTB quartets. I'd recommend the work being performed with the full 12-part compliment, as the third quartet (parts 9 through 12) are quite important and are not mirrored in the upper eight trombones or the organ part. -cdp
