Age is just a number.

Ask island musician Larry Jackson. He’s celebrating his 44th birthday with a heavy metal concert — and not as an attendee, either.

The Howling Gods guitarist said his group is set to share the stage at Grange Hall (10340 Madison Ave.) Saturday, Sept. 15 with The Accused and Supercult — featuring special guest drummer Chad Channing, of Nirvana — in a one-night-only triple header heavy/thrash metal fest at 7 p.m.

Admission is $7 per person, payable at the door.

The night promises to be half birthday party and half island musician reunion, Jackson said.

“All of the bands have a lot of ties with Bainbridge Island history,” he said. “We got Supercult opening [and] that has Rob Day from Stonecrow, a thrash metal band from BI in the ‘90s, and Andy Caro from the first hardcore punk band from B.I. March of Crimes.

“Their drummer at this show will be Chad Channing from Nirvana,” he added.

Channing is, of course, best known for being Nirvana’s drummer from 1988 until 1990. The group famously recorded and released their debut album “Bleach” in 1989, and Channing played drums on the entire album except “Floyd the Barber,” “Paper Cuts,” and “Downer,” which featured drummer Dale Crover from an earlier recording session prior to Channing joining the band.

He eventually left, by mutual agreement, amidst reported creative differences and now sings and plays bass in the band Before Cars.

Next on stage is Howling Gods and the birthday boy himself.

“Howling Gods’ [island ties include] me and Edward, our drummer, formerly of Christdriver and Subvert,” Jackson said.

Finally, finishing the night’s lineup, is The Accused.

“The Accused’s ties to Bainbridge Island are extensive,” Jackson said.

“Andy Caro was their roadie. When I met them, at age 12, Steve Nelson from BI was their drummer. [They’re] an amazing punk/thrash metal band that is climbing up the ladder and landing shows — like opening for Lamb of God next week.”
