Summer tours are a grueling ordeal for any band, though not many have the stamina and intestinal fortitude of Glassjaw. Despite the knockout-prone connotation of their name, this hardcore quintet from Long Island, New York ("Strong Island" to the scene's constituents), will go the full 15 rounds this summer.

Following its current tour, which winds down June 25, the band will make the rounds on both the Warped Tour and Ozzfest until back-to-school time. The Warped trek kicks off June 21 in Nampa, Idaho, and Glassjaw hitch their wagon to the caravan six days later in Bonner Springs, Kansas, according to their publicist. The group stays on the roving music-meets-extreme-sports festival until July 14; then they latch onto Ozzy's extravaganza from August 10 through a September 8 finish in Dallas.

Playing such double duty might give some bands multiple personality disorder, but singer Daryl Palumbo isn't concerned with tweaking Glassjaw's tunes to suit two markedly distinct crowds.

"I'm not really worried at all, because when you come to our shows you'll see that the attendance is exactly half and half," Palumbo explained. "Half kids that would attend the Warped Tour, being more of the punk- and hardcore-leaning, and half kids that are of the whole Ozzfest walk of life — the kids that listen to the more larger-label-sounding metally bands."

In an era marked by almost as many genres and subgenres as bands themselves, the only way one group can be all things to all people is by not fretting over how to accomplish such a feat.

"We're going to play what we play," Palumbo said of Glassjaw's strategy. "The thing is, with our band it's not just from song to song. Our music spans the spectrum of light and heavy. But it's within songs that span the spectrum of light and heavy. So whatever our set's going to be, it's going to be Glassjaw no matter what."

All this roadwork is to promote the band's second album, Worship and Tribute, due July 9. Ross Robinson (Korn, Slipknot) produced the LP, the group's first for a major label, as well as its predecessor, 2000's Everything You Always Wanted to Know About Silence, homing in on the tumultuous impetus that later became scream-addled cathartic outbursts.

The LP's title serves as an homage to what shaped the band — folks ranging from Bad Brains and Tori Amos to their friend Michael, Palumbo's father, Frank Zappa (Palumbo's "favorite musician and political figure") and Morrissey ("the single force that invented nose-in-the-air punk"), while providing commentary on the post-modern world.

"These are all just mammoth forces that have shifted the tides politically, artistically, visually, musically in so many ways," Palumbo said of his influences. "And these people move me and force me to create."

But the title "more directly plays into [the idea that] collage is the art form of the 21st century," he added. "An old friend of mine told me that, and it's absolutely true. Everything we do, whether it's cited or whether it's footnoted or whether it's even intentional is a collage of our influences. We're all just a sum of our influences."
