Everything old is new again.

But, like any good speakeasy cocktail, it’s best served with a twist.

The cool combo of classic Swing Era sounds and contemporary dance music brings a rocking reimagined version of the Jazz Age to Seattle stages courtesy of the six-piece ensemble Good Co, the nation’s first “electro swing” band.

Just what is electro swing?

It’s the jitterbug meets dub step.

It’s flappers on Facebook.

“It’s Cab Colloway meets Daft Punk,” explained Good Co founder Carey Rayburn. “It’s like ‘20s jazz meets the dance music of today.”

Good Co will bring their “new old sound” to the Space Craft stage on Friday, May 20, as part of a doubleheader concert event with General Mojo’s. The band uses beatboxing harmonicas and regular impromptu jam sessions to combine “the era of illicit booze, jitterbugging flappers, and underground speakeasies with the funky beats and the electric sound of today’s dance music.”

Rayburn said the group’s founding idea was as simple as the combination of his two primary musical influences.

“I’ve always been a big fan of vintage jazz, like ‘20s and ‘30s jazz, the early stuff,” he said. “It’s really raw, American kind of stuff. And I’m a huge fan of electronica, too.”

The band itself is a mixture of Seattle players, from one side or the other.

“Half the band is UW grads and the other half is Cornish grads,” he added. “I met the different people in the band just by playing with different groups. Our pianist I met playing salsa, our bassist from playing jazz, our vocalist, Sasha [Nollman], from doing an Americana band. I put together a group of all the best musicians I knew.”

Originally from Seabeck, Rayburn earned a bachelor’s degree in trumpet performance and a “masters in accruing student debt” at the University of Washington before setting out to make a career as a trumpet player and composer. He was wildly influenced by the first samplings of something a friend of his called electro swing music, which was gaining popularity in Europe.

Despite its foreign roots, Rayburn knew right away that this new sound was based on a strictly American style. With the continued success of musicals such as “The Drowsy Chaperone” and “The Wild Party,” flashes of Swing Era aesthetic in today’s fashion trends and the critically acclaimed most recent remake of “The Great Gatsby,” Americans seem unable to get enough of the nostalgia and romanticism of the Roaring ’20s in any form.

Hence, Rayburn decided to set about bringing the party home.

“It’s something that’s kind of built into our psyche as Americans,” Rayburn said. “We hear that sound and — even though most of us didn’t grow up with it — it’s kind of always been a part of our character. So we recognize the sound, it’s got a feel, and we know it as a uniquely American sound.

“It was meant to be party music, really,” he said of the Jazz Age soundtrack.

“Just specifically for having a good time. I think you can really hear that in the music, and that’s why it really works well combining it with dance music of today because they both serve the same function.”

Rounding out the Good Co roster is Dune Butler, Michael Conklin, Colin Pulkrabek and Jake Sele.
