The immediately recognizable, rise-and-fall riff to The White Stripes’ “Seven Nation Army” poured forth from a classroom near the entrance of Westside Village Magnet School at Kingston Elementary early on a recent Thursday.

The Westside Village Roots Rock Band, the “varsity squad” of the school’s extensive music program, rehearses there every Tuesday and Thursday. On this particular day, the group featured a drummer, bassist, two keyboardists, three electric guitarists and six vocalists practicing for their annual performance at the Bend Roots Revival.

Though the door was shut, the four walls barely contained the massive sound as the band fired off songs such as “Smells Like Teen Spirit” and “Come Together” in quick succession. Lead instructor Patrick Pearsall, joined by Mark Ransom and Aaron-Andre Miller, offered suggestions to the musicians between songs, but other than that and some light joking around, the band played through.

“This was the third day of the class this year, and we played 40 minutes of music that sounded pretty good,” Pearsall said after the session. “We do this at other schools, too, and that doesn’t happen necessarily — this culture of the kids who have been here. When we got here this year, we didn’t talk about, ‘OK, guys, we’re gonna sit down.’ We didn’t stop to learn how to play the songs or anything like that.”

Bend Roots Revival, which will feature more than 115 local and regional artists on seven stages, returns to the Deschutes Brewery warehouse Friday and runs through Sunday. The Westside Village band will perform at 12:45 p.m. Saturday on the BIGS Stage.

As usual, proceeds from donations, food and beer sales at the festival will benefit parent organization Rise Up International’s music and arts education programs in Bend-La Pine Schools — including Westside, Cascades Academy, Realms middle and high schools, the Tamarack Program (including students from Riverbend Middle School and Chamberlain High School) and Bend International School.

As Rise Up’s first program, started in 2005, Westside Village represents Rise Up’s educational programs at Roots. The set, one of several the band performs throughout the school year, serves as a passing-of-the-torch moment to launch the new year, with alumni invited back to perform alongside current students in grades four through eight.

Drummer and seventh-grader Parker Garcia, 12, will play his fourth Roots Revival this year.

“I remember when I was younger, I would watch the band and be like, I’m gonna do that when I’m older,” Garcia said.

Garcia joined the band when she was in fourth grade after going through the school’s early music education, which focuses on body rhythm and basic instruments such as hand percussion, marimba and ukulele. The program is based on the Orff Approach, which is a developmental approach to music education based in movement, speech and play.

“As we develop as humans, there’s also an evolution of the way we learned to mimic the sounds in the world,” said Ransom, founder and director of Roots. “It began with our own internal heartbeat and the sounds in nature that we could (imitate) — our voice and body rhythm. So that’s really where we start all the kids when they’re in kindergarten, pre-K, so they’re working with body rhythm and melody without knowing it. … And they’re looking forward to the time when they get into fourth grade, when you can do something different and you can be in the guitar class or you can do piano and you can do something in the ensemble.”

Westside Village isn’t the only student band to play Roots every year. Anything But Vanilla, the top ensemble in Cascade School of Music’s Rock U program, will perform on the 4 Peaks Stage at 12:30 p.m. Saturday.

The band’s five members, who range in age from 15 to 18, are veterans of previous years’ incarnations and have performed at Roots before. Rehearsals for this year’s performances began only a few weeks before Roots, on Sept. 12. (Cascade ensembles play three main shows throughout the year at McMenamins Old St. Francis School, Broken Top Bottle Shop and the Tower Theatre, while Anything But Vanilla plays extra events such as Roots and last year’s Fall Festival.)

“It’s basically like a tour band where they play the exact same stuff for a full year,” guitarist Elijah Tran, 17, said, “only we didn’t travel at all.”

At a recent rehearsal, the band worked out what few kinks remained in the set. Roots aficionados would probably recognize the quintet’s muscular takes on Derek and the Dominos’ “Layla” and Kansas’ “Carry on Wayward Son.”

“We’ve been changing up the songs, too, so they’re not exactly the same,” bassist Lalana Tran, 15, said. “Like for (Blackstreet’s) ‘No Diggity,’ we are actually having our drummer (Tim Hakala, 16) — he has a hidden talent, which is beatboxing.”

Kids who take private music lessons will also get chances to shine on Roots stages. Jazz instructor Georges Bouhey and local violin prodigy CJ Neary will once again lead the group Jazz Bros. at 4 p.m. Saturday on the BIGS Stage.

In past years, String Theory Music owner and Moon Mountain Ramblers mandolinist Joe Schulte has held mini-recitals for his students at Roots. His Moon Mountain bandmate, percussionist Dale Largent, wanted to do something similar, and this year will be the fourth year that his students perform a recital.

Two of Largent’s 16 recital students, sisters Lucy and June Poling, started a recent lesson with Largent by singing and playing through Matisyahu’s “One Day.” Lucy, 9, played ukulele, while June, 7, felt out the chord changes on piano. For the next song, Charli XCX’s “Boom Clap,” Lucy moved to the drum kit.

The girls have studied with Largent for the past two years, and played in Largent’s Roots recital last year as well. They pick the songs they want to play, Largent said.

“Half of the songs they pick out I’ve never even heard,” Mara Richardson, the girls’ mother, said. “But I think that that’s really key to their enjoyment of all this.”

June said her favorite part of playing music is “how fun it is to hear the sound come out.”

“Another thing I like is just to press on the keys and hear how it matches any song that I chose,” she said.

“I think you’re saying you know what it should sound like, and then your fingers move and it sounds like it should sound like — and it’s kind of like magic,” Largent replied. “I put that word in there, but is that kind of what it’s like? Or it’s special that way: Look, I’m doing it, I’m doing it, it’s right.”
