"It's a really cool event," said Foothill band director Josh Butterfield, who participated as a musician himself in the 1990s when he was a student at Foothill.
"We're the host band so we're not competing," he explained, "but as a band we travel around almost every Saturday to compete in field and jazz competitions at other high schools."
The parade begins at 8:30 a.m. with about 45 bands marching down Main Street starting near Amador Valley High. Pleasanton Unified School District's new Superintendent Parvin Ahmadi will be the grand marshal. It is estimated that the parade will continue through 1 p.m.
Bands will perform for five minutes in front of the judges, professional music educators from the Northern California Band Association, who will be across the street from Dean's Cafe, 620 Main St. When each band arrives at Angela Street, its percussion portion will step out to perform for a judge at that intersection.
Meanwhile 20 concert bands will be competing at the Amador Valley High theater and multipurpose room from 7:30 a.m.-12:30 p.m.
"In the afternoon there is an awards ceremony that we host at 2 p.m. on our field," said Butterfield. "It's for all of the parade and concert bands that have competed."
These events are free.
Then at 4 p.m. about 24 show bands will take over the field at the Foothill football stadium to compete until 10 p.m.
"Each group gets five minutes in the parade, but for the field competition they have a 15-minute performance slot," Butterfield said.
A food court will include Coldstone Creamery, Cooler than Ice, Nellie's Catering, Peter's Kettle Corn and Rodney Chun Chow Mein.
It's a great family event, said Butterfield.
"I have a 4-year-old who comes to all these," he noted. "It should be a pretty good turnout."
The event is the largest fundraiser of the year for the Band Boosters, and it helps pay for new instruments to replace those that have worn out as well as for instructional assistants. The evening show costs $10; students and seniors are $7. Children 5 and under are free.
"Altogether we're hosting over 65 bands from all over California," Butterfield said. "It's pretty labor intensive to host 4,000 people, to park buses for 30 bands at Foothill."
He credits the organization to the Band Boosters and this year's chairman Terry Abbey, who is coordinating with the city and the Police Department.
Foothill High School has about 200 students in the instrumental program, Butterfield said.
"Pretty much every student and every parent of every student volunteers on this day to make it happen," he added.
