A new monthly all-ages music jam, “Fourth Friday Song Circle,” begins tonight from 7:30-10 p.m. at Yeomalt Cabin, 900 Park Ave.

Bring your guitars, voices, ukes, fiddles, mandolins or any other instruments, for an old-fashioned songswapping song circle. Feel free to come just to listen.

No admission cost, but donations are accepted.

Go ahead.

Add one more thing to the long list of music events that Eddie Williams has a hand in.

He already handles sound and recording at Island Music Center. Not only does he work the mixer at the Treehouse Café, he’s the one landing the jaw-dropping talent that’s been parading through Lynwood Center of late.

He is the official sound man for the Bainbridge Island Metro Park & Recreation District, for events such as the Concerts in the Park series, the Battle of the Bands and No More Schoolapalooza. He’s worked the sound at the Harvest Fair, the Bluegrass Festival, last year’s July 3rd Dance. He’s recorded or furnished sound for Bainbridge Performing Arts, St. Cecilia’s Choir, Grace Episcopal Church, The Chamber of Commerce, Bainbridge High School, events at IslandWood, auctions for Hyla and Camp Siberia. Go ahead, take a deep breath. He’s recorded countless CDs for island musicians, both established and emerging like the compilation of Seabold Second Saturday performances he recorded, “Setting the Woods on Fire,” and last month, Bainbridge songwriter Bryan Dever’s CD.

If that wasn’t enough, he’s got a new venture: a monthly jam session, “Fourth Friday Song Circle,” at Yeomalt Cabin.

The new song circle takes after the old Coffee Cantina jam nights, in which Willams and many other island musicians participated.

“The feeling, much like the Seabold Second Saturdays, was familial,” said Larry Dewey, one of the original Cantina crew.

Unlike an open mic format though, in which musicians take turns getting up in front of an audience, a song circle lets all the musicians join in every song, picking up a piece here and there or jumping in on an old favorite.

“It’s communal in the real sense of the word,” Williams said. “It’s a teamwork thing.”

Leadership rotates around the circle with each person introducing a song of their choice.

“It’s not a performance,” he said. “It’s just about working together and once in a while – every now and then – there’s this energy.”

The venue this time around will be Yeomalt Cabin with its woodsy interior and roaring fireplace.

“The Cabin is magical,” said Shannon Buxton, the park district’s youth and teen coordinator. She’s hoping that young musicians who know Williams via his work at the Teen Center will feel comfortable joining the song circle. The younger musicians will bring fresh energy and may even find a mentor among the “old timers.”

Go ahead. Jump in.

Treehouse Rock

If you’re looking for world-class nightlife, names like The Tractor Tavern or the Showbox come to mind. Then there’s the Triple Door and the Treehouse Café – say what?

Yes. The Treehouse Café. On Bainbridge Island.

“Sort of preposterous.” That’s how Williams describes being able to see a musician of Greg Brown’s caliber in a venue as intimate as the Treehouse.

It all started when Mike Sciacca, aka Ranger’s dad, and guitar maestro for “Ranger and the Rearrangers,” introduced Williams to Treehouse owner Arnie Sturham during Taste of Lynwood.

Sturham was just looking for someone to install a sound system for the newly renovated and expanded cafe.

“Our taste in music was similar and we worked really well together,” Williams said.

Williams had booked bands on a much larger scale in Los Angeles and wrangled an opportunity to draw acts playing in Seattle. First, he snagged LeRoy Bell in October 2010, followed by Star Anna. Since then, there’s been a consistently impressive line up: The Paperboys, Vicci Martinez, Massy Ferguson. When they booked James McMurtry – seriously – Seattle Weekly gave its second nod in a year: Bainbridge Island was on The Map.

“You could live in New York City and not experience this kind of thing,” Williams said.

The Clumsy Lovers? Left Hand Smoke? Greg Brown back again. And if you’re shocked by that, wait till you hear who might be next (hint: Michelle).

The Treehouse is not the typical music venue with a built-in group of regulars. Bainbridge is “event particular” Williams said diplomatically.

“The peculiar pool of patrons on Bainbridge is a small and discriminating one,” warns the Treehouse website to prospective acts. “They come out… to see acts they’ve never seen on the island before, but once their curiosity is satisfied….”

Not only will you be able to pick from top acts, soon you’ll be able to pick your seat, too. Look for an upgrade on the Treehouse website that allows you to peruse a seating chart and buy tickets online.
