Most musicians long to get on stage with some compatriots and make some noise, but not everyone can assemble a band, much less find a good gig. Open jam nights offer a chance to scratch that itch for beginners, basement savants and seasoned session players alike.

Most musicians long to get on stage with some compatriots and make some noise, but not everyone can assemble a band, much less find a good gig. Open jam nights offer a chance to scratch that itch for beginners, basement savants and seasoned session players alike.

Improv-heavy blues and jazz dominate the open jam circuit, though everyone who seeks it can find a creative outlet somewhere. For instance, recent Ohio State music school grad Evan Oberla is moving his genre-jumping improv night from Rumba Cafe to Ruby Tuesday this January. Though Oberla's RFG Quintet plays jazz, "the premise was not to be just a jazz jam session," he said.

There's potential for magic every time musicians collaborate, though there's also the chance the session will run off the rails.

"It's never a train wreck," said Pete Mills, who helps run the longstanding jazz jam at Park Street Tavern, the former site of the famed 501 Jazz Club. Mills cited jazz's long tradition of sit-in sessions. "Sometimes it works out great. Other times it's different. It's never terrible."

Ultimately, that spontaneity - and the endless possibilities that come with it - makes this tradition tick.

"You never know," said Buzz Chewning of the Snake Kings, who supervises the Hey Hey's Thursday blues jam. "No two weeks are the same. And that's actually a very nice thing, really."
