This is an old video I had lying around of a full rehearsal run-through of El Camino Real by Alfred Reed with the AHS Wind Ensemble during my senior year. The contra part is the opposite of eventful, likely being a transposed tuba part but they give you less somehow :D
.
If you hear me rushing in the beginning it was likely because I was overcompensating in an effort to not to be behind the beat.

Anyways, hope you enjoyed! (And I hope you could hear me lol)
