Mohawks gouging eyes out, fists pumping and a bunch of people chanting "Oy! Oy!"

For the most part, that is what can be expected at a Voodoo Glow Skulls concert, but lead singer Frank Casillas thinks tonight's show at Crowbar, 420 E. College Ave., will display a more diverse fan base.

Backside, Ann Beretta and Grade will open for the Skulls after doors open at 7 p.m. These bands draw influence from a wide variety of genres that mix nicely with the Skulls music.

"We mix it up with bands that are someone else's audience," Casillas said. "We're all very Southern California. . .except we all wear glasses because we're very blind."

The band consists of the Casillas brothers: singer Frank, guitarist Eddie and bassist Jorge. Joining this family bond is drummer Jerry O'Neil and trombone player Brodie Johnson.

The Skulls' look is rather plain in comparison to the ska-punk music the band produces.

"There are no costumes or pyrotechnics; just baggy shorts with sneakers and T-shirts," Casillas said.

The do-it-yourself attitude that the Skulls live by is the root of its twelve-year progression.

Casillas explained that State College is a "really cool stop for a band at our level" and that the Crowbar is a "good venue."

The Skulls have a new album, Symbolic, which fans can count on hearing at the show. But their new touring and performing concept is to play more of the older songs for their fans.

"It's difficult to get a mainstream audience. We rely on hustling and word of mouth," Casillas said.

In the punk rock world, success is selling from 5 to ten thousand records, Casillas said. However, he doesn't seem to mind missing the mainstream scene.

"The expectation is not that high. There's not so much pressure," he said.

They like to incorporate diversity into their music by listening to ideas from other people in the business.

"We're definitely punk. And we've always toured with punkers," Casillas said.

Twelve years of playing and six albums later, the backyard party music travels all over the United States, relying on word of mouth.

The Skulls formed in the late 80s and slowly added a horn section, which may grow even larger. Then, in the early 90s, the band became one of the most popular ska-punk bands on the West Coast. Now they're invading the East Coast.

Even with the Warped Tour to compete against, the Skulls are pretty happy with the turnouts at the shows, Casillas said.
