The Stampede Drum Line and the Broncos Brass have been a staple sound at Sports Authority Field at Mile High for years. Started as the Stampede Drum Line in 2003, the group was one of the first NFL drum lines, a number that has now moved in to the low twenties. Tailgaters can hear their favorite pep numbers played by the professional musicians, and fans in the stadium start every game with the band playing the Denver Broncos’ fight song.
