“Revolution, revolution, revolution …” were the chants coming from the slightly less-than-full Convocation Center crowd Friday night. The fans were showing their enthusiasm and appreciation for the new-age reggae band Of A Revolution.

The show started with opening act Toothpick, who got the crowd ready for O.A.R. with an acoustic-based hip-hop set. The highlight of his set was the performance of a Slick Rick song accompanied by O.A.R.’s drummer Chris Culos and saxophonist Jerry DePizzo.

Following a short break, O.A.R. took the stage to an arena full of cheering fans. The set started with some of O.A.R.’s older songs and then slowed to a pace dictated by music from its new album, “Between Now and Then.” The band asked the crowd for permission to play “52/50,” a song it never had played live before.

The show then continued with what lead singer Marc Roberge called “real old songs,” but these seemed to be the ones fans paid the most attention to. The set was highlighted by a cover of U2’s “Sunday Bloody Sunday.”

“I love the way this band was able to pull the audience into the performance,” said Andy Mistretta, a senior business management major.

The band did a couple more songs before performing its hit song “Crazy Game of Poker.” The popular song was highlighted with a guest appearance by Toothpick, who provided hip-hop flavor to the song and induced the crowd into chants of “revolution, revolution, revolution.”

The band then finished its set and returned for a two-song encore.

After the show, visiting Illinois State University student Tommy Korth said, “The show was rocktastic, and I could feel the music going through my body.”
