"A lot of his lyrics are based on Jewish mystical concepts and improving oneself and the world," he said.
"The themes are similar to themes in traditional reggae music, such as redemption from exile," Meretsky added.
Despite the strongly religious content of his original lyrics, Matisyahu's fan base tends to transcend boundaries between specific denominations and faiths.
"My music is not for Hasidic Jews," Matisyahu said. "It is aimed for people that listen to that type of music, and it's generally not Orthodox people. There are a ton of Jews that are into my music, but it tends to be more secular."
Though the event is presented by Chabad, the performance is by no means directed primarily to those with a Jewish heritage.
"It's definitely not limited to the Jewish student population," said Chabad President Jennifer Putterman. "They might find it unique to their culture, but anyone can enjoy the music."
Though his lyrics are often derived from mystical texts, Matisyahu leaves his ideas open for personal interpretation.
"Some of his lyrics are fairly general, focusing more on general spirituality," Meretsky said. "He tries to break it down in a way that people can relate to."
Matisyahu's fame has been steadily rising since the 2004 release of his debut album, Shake Off the Dust ... Arise, which has made various top 10 lists.
"The main theme of the album is trying to see through the world to see the spiritual dimension, and trying to become sensitive to godliness and less connected to materialism," Matisyahu said. "Everything in this world is not fragmented as it seems, but is all connected, ... is all a part of God."
Overall, though Matisyahu sings about deeply religious concepts, his game plan is not to convert his listeners.
"My goal for making music is to try and uplift and be a positive voice that people can relate to," Matisyahu said.
Crowbar Operations Director Dave Wells worked with Chabad again after Matisyahu's successful performance last spring.
"If you take a look at the Crowbar, it has a wide diversity of music," Wells said.
"So this is just more of that diversity ... but the music and what this guy brings to the table is just incredible," he added.
Despite the recognition he's been receiving in the past year, Matisyahu remains rooted in his spirituality.
"Fame is not that big of a deal ... it's not that noticeable," Matisyahu said. "It's real, and everything that happens in life is real. Nothing is fantasy, even if it's something you've been looking forward to. It feels good, but life is life."
