This Saturday, the State College bar scene will undergo a massive change -- a "Revision," if you will.

No, last call hasn't been extended, and the entire town hasn't gone smoke-free. The Revision in question is actually a four-piece jazz/funk group from Ithaca, N.Y., and the band will be performing at Zeno's, 100 W. College Ave.

Revision formed at Ithaca College about six years ago, when its members were freshmen.

Bassist Jason Pratt said the group came together through a process of jams and chance meetings. At the end of that first year of college, the group played its first gig with its current lineup, which has remained the same ever since.

"It's incredible how time flies," Pratt said. "Playing together for that long really gives you a lot of time to jell with the guys you're with."

But even though its members share a common college, Revision is the product of four musicians with quite different backgrounds. Pratt said he played "anything and everything" in high school but came from a heavy alternative rock background. Guitarist Nick Bullock switched from an interest in basketball to guitar during his high school years, eventually studying jazz performance in college. Keyboardist Jon Petronzio is classically trained on his instrument and drummer Devon Reehl's playing has a rock/funk feel that Pratt said locks up with his own style.

"Once we got into college, all these different attributes all kind of cultivated together and kind of meshed," Pratt said.

Now that the group's members have graduated, Revision is no longer just a bunch of college kids. The band performs regularly in several major cities up and down the East Coast. But a band can never truly forget its home base, and as evidenced by songs such as "Ithaca Weather," Revision is still a gorges group.

"We definitely don't consider ourselves a college band anymore," he said. "But we met here, we still live here, we operate out of here, the music that we play is music that jelled in college."

Even though Revision is still staying true to its college roots, the Penn State audience isn't the only one it caters to. Pratt said he's seen fans as young as 10 and as old as 75, though he believes it shouldn't be about any specific demographic.

Still, Pratt said he has noticed that his band's previous performances at Zeno's have increased in popularity.

"Each time we came back, everybody there before brought a few friends to the next show," he said. "We're playing on better nights and the place is filling up."

Dave Staab, Zeno's general manager, said he has noticed this positive trend as well.

"The biggest indicator for me is when people ask during the week when that band's coming back, or tell me mid-show, 'You gotta bring these guys back,' " he said. "Revision and The Blue Method are the two bands that have gotten the most customer comments."

Staab described Revision's sound as fitting in with some of the other acts the bar has hosted recently.

"It's a funk jam band with some jazzy inflections," Staab said. "Bands that we've been getting have been upbeat, you know, on the funky side of things ... with a dance beat and some high energy coming from the stage."

Pratt said that that energetic vibe is important to the Revision live performance. And semi-clever puns on the name aside, "Revision" actually sums up a great deal of what the band is trying to accomplish, he said.

"It's kind of interpretive. Since we all have different backgrounds, it's kind of like we're taking a different look at where we came from," Pratt said. "You're starting at a point where you've had so much great music come before you, and you have to appreciate and pay homage to what came before. ...

"What makes us different is you have four very capable musicians that came from different backgrounds that really have jelled together and just know each other."
