When you’re listening to the band IT perform “The Juice,” don’t be surprised if you have a flashback to a movie you’ve seen before.

“The Juice” is about the movie “Beetlejuice,” says Todd Cooper, co-founder of and guitarist in the band.

“In that song, there are a few lines I have taken from that movie,” says Rick Hoffman, co-founder of the band and its vocalist.

The majority of the songs the band writes and performs are based on movies, and many of those tunes will be on the playlist when IT takes the stage at 10 p.m. Dec. 20 at The Rendezvous.

“We’re all a bunch of movie geeks,” Cooper says.

Besides Cooper and Hoffman, those other “geeks” include Will Stuck, (yes, the children’s librarian), bassist; Ric Howard, guitarist; and Danny Thompson, drummer.

Cooper and Hoffman formed IT about three years ago. Before then, Cooper had been a member of the local group Full Power for almost 20 years. Cooper says IT will play “anywhere that will have us.” After the performance at The Rendezvous, the group will head down to the Beaumont Club in Kansas City on Sunday, Dec. 21, for a battle of the bands competition.

Since the IT guys love movies, it’s probably natural that they would write and perform songs based on them. Hoffman says the members agreed that topics such as politics and growing up already were covered by most other bands.

Although “The Juice” is one of his favorites to perform, Hoffman says he feels a personal connection to the song “American Vietnam.” That’s due to the fact that he is a member of the Air National Guard and has been overseas three times, including two times in Iraq.

“We wrote that about the movie ‘First Blood’ with Sylvester Stallone,” he says of “American Vietnam.”

The band also does a few cover songs when in concert, including Johnny Cash’s “Folsom Prison Blues.” And audiences may be lucky enough to hear one of its most recent compositions, “Everybody’s Gotta Go,” which the band wrote and recorded for a children’s charity CD (the band is also waiting for the release of its own CD).

“It’s kind of a potty-training rock and roll song,” Cooper says.

“We’ve played it three times now,” Hoffman says. “The first time we played it, it got an overwhelming response.”

What can you say, except that’s IT.
