It's a sold-out rock show. The crowd is lining up at the doors more than an hour beforehand.
It's Staff Infection's biggest gig of the year. The band opens with "Smoke on the Water," awash in fog, lasers and strobe lights, and throughout the two-hour set, the crowd of 1,000 breaks into ecstatic applause and wolf whistles between numbers. They close with "Stairway to Heaven."
Sound too cool for school? Not quite.
Staff Infection is made up mostly of teachers at Anoka High.
The band got its start in the mid-1990s, although one of its first performances drew mixed reviews. At a pep fest, Staff Infection got the students so revved up that band members began crowd surfing.
"We played one song, 'Proud Mary.' Our principal thought we would lip sync. They were shocked when we tore into that song and rocked it," said lead singer and guitarist Pat Coffee, who teaches industrial arts. "They came up afterward and said, 'That's the last time you'll be playing pep fest.' "
The band has since had its hall pass restored. Each year, they play a pair of charity concerts at the school. They also perform at local bars on their tongue-and-cheek "It's a Small World Tour."
"They're awesome," said Principal Mike Farley, who wasn't principal during the pep fest episode. "I don't know that I've ever been at another school where they've had [a rock band]."
