Devorah, aka “Firecracker,” that whirling dervish of musical energy and talent, has just spun-off her third music compilation, “Irrepressible,” a 10-track CD that marks a sea change in her music, featuring several songs of her own writing.

Devorah’s contribution to the local music scene can be measured in decades and anyone who has ever heard her sing knows full well how surprising — shocking — it is to hear that much energy flow like a fire hose out of her diminutive 4-foot-11-inch frame.

And then there’s her voice. “Wow.” is a common response.

Devorah is performing Thursday at this year’s Pig War Picnic and will be joined by several of her best musician friends she’s known over the years. Some of them helped her on this most recent CD, of which she is clearly excited.

“This disc reflects very clearly the essence of what my life has been like so far,” Devorah said. “Emotionally, it expresses the feelings and issues that people of all ages feel. The songs reflect questions we ask ourselves as people and what we’re doing in our lives.”

The release is a mixture of songs she’s written herself, as well as a few covers: “Cry Love” by John Hiatt, “I Thank You” by David Porter and Isaac Hayes, and “Crystal” by Stevie Nicks. She does more than justice to all three, coloring them with her own shades of vocal colors.

“I’ve never held back, musically,” Devorah said.

Devorah’s performance features some of the Northwest’s most sought-after live and studio musicians, who, naturally, have known Devorah for years. Her producer, Chad Quist, will perform with her, as will Douglas Barnett on bass. Singer and songwriter Steve Trembley will accompany on guitar.

Six-string violin soloist and featured artist Geoffrey Castle will take the stage with Devorah this year, as will Eric Robert on keyboards and Doug McGrew on drums.

Devorah will perform at the Pig War Picnic between noon and 1 p.m. Copies of her new CD will be on sale.
