This weekend's Nittany Booking show is bound to get vocal.

Good Old War will join California Bay Area band Audrye Sessions at 7 Sunday night for a live performance at SoZo, 256 E. Beaver Ave.

Each band displays distinct vocal stylings as an integral part of its sound. For headliner Good Old War, this sound can be described as a "folk rock extravaganza," said Dan Schwartz, guitarist and vocalist for the band.

Schwartz added the most important part of the band's music is the explicit use of three-part harmony that riddles each of the band's songs.

"We're doing what we all always wanted to do -- singing all the time," he said.

He added the band not only displays vocal skill, but also flavors the music with pop sensibilities that encompass its short songs with catchy lyrics.

Garrett Bodgen, promoter for Nittany Booking, said Good Old War's vocals are the band's best feature.

"When you're a three-piece band, you almost need to use your vocals as another instrument," he said. "They do it perfectly."

Previously, when the band was in State College and rehearsing in a room at SoZo, Bogden heard the band and said he thought he was listening to the radio. In actuality, the band was using just one acoustic guitar and vocals to create its sound.

"It's just so simple, it's perfect," he said.

Ryan Karazija, vocalist and guitarist for Audrye Sessions, said his vocals are interesting for other reasons.

"If people think I'm a girl, it's OK," he said, referring to the fact he usually ends up singing in his higher range while the band is playing or working on songs.

"It doesn't bother me," he said. "This is how I sing."

Although Karazija's vocals define the band's sound, he said he is actually not a big "talker" in front of people.

"I'm not the guy who is going to come up and tell you a joke," he said. "I'm not a talker. I perform."

This State College performance for the band is one of the first stops on its tour to support the band's first self-titled full-length album.

The band will use this opportunity to expand its horizons beyond the Bay Area enclave.

"To be successful you have to get out and tour," Karazija said. "We can't stay in our own little area, because people will stop coming because there's so many shows."

Bogden said he hopes Sunday's show will turn a few people on to this band, which is new to State College. He added its similarities and differences with Good Old War will be complementary to the performance.

After Good Old War opened for both Ace Enders and Charlotte Sometimes at SoZo in past shows, Bogden said this time around, the band is ready to headline.

"Their music is so universal, anyone can listen to it and start tapping their toes and get into it," he said. "Their potential to mainstream appeal is huge."
