Fans of acronyms and rock music alike should keep Feb. 6 open because the indie rock band Of a Revolution, better known as O.A.R., is coming to the Convocation Center.

The band’s stop at NIU is one of many college venue concerts scheduled on its tour to promote its most recent album, “In Between Now and Then.” The CD, released last May, is O.A.R.’s major-label debut after years of being known as one of the most successful indie bands.

Kevin Selover, director of marketing for the Convocation Center, anticipates drawing a younger crowd.

“I am expecting a lot of people in the 25-and-under age group,” Selover said. “I’d even say many high schoolers could be expected to attend. They have a pretty good following. It is just that it is an underground following.”

The underground following started when rhythm guitarist Marc Roberge and drummer Chris Culos started jamming together when they were classmates at Wooten High School in Rockville, Md. Lead guitarist Richard On and saxophonist Jerry DePizzo later joined the band. They became increasingly well-known as they made the transition from a fraternity band at Ohio State University to nationally-known headliners who have performed on “The Late Show With David Letterman” and “Late Night with Conan O’Brien.”

Christine Nicholson, a junior communication major at the University of Iowa, saw an O.A.R. concert at her college and came away impressed.

“It was a lot of fun,” she said. “They are really animated on stage. It’s fun when you are seeing them live because you can sing and dance and stuff like that. There is a lot of crowd interaction and involvement. They are a genre all their own.”

Concert promoter Don Kronberg said the band depends on word-of-mouth from people like Nicholson

“O.A.R. is more of a grassroots- type marketing effort because they don’t get a lot of radio airplay,” Kronberg said. “They really hand it off to their fan clubs and street team members who spread the word with posters and fliers and other types of advertising.”

Freestyle rapper Toothpick will join the band for the concert, which will start at 7 p.m. Feb. 6. at the Convocation Center. Tickets, which are $25 for students and $27.50 for the general public, are on sale at the Convocation Center box office, all Ticketmaster outlets and www.ticketmaster.com.
