I realize that I'm on a guitarist forum, but in addition to playing guitar, I also play trombone and write music for concert band, and here's a video recording of my University's band (with me conducting) playing a piece I wrote, based on a hymn tune (Sweet Hour of Prayer) and some Native American drum and vocal music. Go to 2:00 to skip me talking.

Very nice. This is one of my favorite hymns - also enjoy playing the melody of this one on the guitar. Thanks for posting the video!
