I was listening to a recording of a University of Nevada, Reno Wind Ensemble piece recently - a piece we also did for a festival when I was a sophomore in wind ensemble (back in the day). Anyway, I posted my parents camcorder footage from it. Not the greatest picture quality, but sounds fine.
Prelude, op. 34, no. 14
On Ancient Hymns and Festal Dances
If anyone else would like to share their concert vids, go for it.
