Sheffield will be alive with the sound of music starting at 6:30 p.m. Friday at Sheffield High School as the “Music on the Mountain” Drum Corps International show steps off in competition.

Six Open Class corps are competing on their way to the final in Indianapolis next month: Spartans, Nashua, N.H.; 7th Regiment, New London, Conn.; Legends, Kalamazoo, Mich.; Raiders, Wayne, N.J.; Les Stentors, Sherbrooke, Q.C., Canada; and Coastal Surge, Myrtle Beach, S.C.

“Parking here is going to be a little bit of an issue,” said Art Lane, chairman for the show that is being sponsored by the Sheffield Music Boosters, and planning for hundreds of spectators. “An overflow shuttle will be running out of the St. Paul Center. We’re encouraging people to use that. The bus will bring them right to the top of the hill.”

There will be a gate at both the top and bottom of the hill to the football field for admission.

“We’re trying to make it as easy access as we can,” said Lane.

Parking at the school will be limited due to the space needed to house the equipment for the six competing corps.

“Gates open at 5:30, so I encourage people to come early, get their parking spot and get their seating. It is general admission seating,” said Lane.

Shuttles, golf carts and a van, Lane said, are available for handicap accessibility to the field.

“We’ll take them right to their seat, just about,” said Lane.

Lane said as of now, there are 1,000 tickets available, of which about 250 have been sold in advance. The bleachers can hold 1,300, and Lane said if necessary, there will be standing room tickets available at a discounted rate.

“People are waiting on the weather,” said Lane. “It’s going to be a beautiful day so there’s no reason we can’t fill the stands.”

Tickets are available at the gate for $15 for adults and $10 for kids.

Lane said the concession stand will be open to the public.
