A lack of general admission seating at a concert venue may be a problem for some bands, but O.A.R. saxophonist Jerry DePizzo says it isn’t enough to ruin a good, live rock show.

O.A.R.’s musical style is generally conducive to dancing, DePizzo says, something an audience at Stephens Auditorium might not be able to do.

There is no general admission area at Stephens Auditorium, so the audience will be assigned seats, which may change the way the audience can participate in the show, DePizzo says.

“It’s a little bit different,” he says. “Is it worse or better? I don’t know exactly.

“I guess that’s up to the opinion of the audience. We will have a good time either way, and we hope the audience does too.”

O.A.R. — an acronym for “Of A Revolution” — originated when singer Marc Roberge and drummer Chris Culos began playing music together in junior high.

As they neared high school graduation, the band released their first album, “The Wanderer,” which is based on a piece of fiction Roberge wrote of the same name.

Since then, the band has released two more studio albums as well as its most recent project, a live album titled “Any Time Now.” The album captures the second night of a two-night show in Washington, D.C.

DePizzo says the album is a good representation of the live show. However, he says there is an element added when one actually goes to an O.A.R. concert.

“It’s taking part in the experience,” he says. “Nine chances out of 10 we don’t make set lists. We base what we play on the audience.”

Another difference between Wednesday’s show and “Any Time Now” will be the addition of new material from O.A.R.’s upcoming album. DePizzo says the band will play two or more tracks from the upcoming release during the live show.

The band has performed with John Mayer in the past, and DePizzo says the band shares an audience with groups like Mayer and the Dave Matthews Band.

Supporting O.A.R. will be Pseudopod and Marc Broussard. DePizzo says O.A.R. members are good friends with both groups and has played with them in the past. DePizzo says he is also a fan of Broussard.

“[Broussard’s] voice — it’s ridiculous,” DePizzo says. “He sounds like a 70-year-old blues man, but he’s, like, 20.”

Though O.A.R. may share a fan base with the two openers and artists like Mayer and Matthews, DePizzo says that musically, O.A.R. has its own genre.

“What we came up with as a label to describe the music was ‘island-vibe roots rock,’ ” DePizzo says. “People need to label things to identify with them … That’s the label we think fits best.”

O.A.R.’s new album is due out May 27 on Lava Records.

Titled “In Between Now and Then,” the album picks up where the last studio release left off, but also heads in new directions, DePizzo says.

“We don’t want to shock people too much,” he says. “But the band also has to grow and progress.”

Therefore, DePizzo says, there will be some songs written in O.A.R.’s familiar style and some tracks which bridge the gap to music “in a direction that people haven’t heard us go before.”

Despite the musical changes, the band will also be playing at this year’s Bonnaroo Music Festival, a three-day festival in Tennessee featuring over 50 artists including The Dead, the revamped Allman Brothers Band, James Brown and The Wailers. The festival is slated to take place June 13, 14 and 15 in Manchester, Tenn.

“We all feel very, very honored to be a part of that,” DePizzo says. “It’s the highlight of our year thus far, being put on the bill for Bonnaroo.”
