Tonight, the Yakima Speedway sidelines the race cars to make room for some live rock 'n' roll.

Dubbed Power Jam, the tribute band triple-play concert features headliner No Quarter, a popular Led Zeppelin tribute that channels the sound -- from "Black Dog" to "The Wanton Song" -- and the look of Plant, Page, Jones and Bonham.

Opening the show are Live Wire, an AC/DC tribute that's played Yakima a number of times; and Drop Dead Legs, a female-fronted Van Halen tribute.

While ticket sales have been slow, promoter Steve Hall is staying optimistic that classic rock fans will show a whole lotta love at the gate.

"I've heard there's large walk-up crowds (in Yakima), which would be good," says Hall, who'd like to do more concerts at the Speedway if there is an audience to support it.

For tonight's all-ages concert, the Speedway will be arranged with the stage on pit row and the crowd on the track and in the grandstands. There'll be concessions and beer available. The gates open at 5 p.m. and the rock cranks up at 6 p.m. at 1600 Pacific Ave.

Tickets cost $16 in advance and are available through Gap West Broadcasting, 509-972-1460; the Yakima Speedway, 509-248-0647; Eve's Garden, 509-575-9566; Ted Brown Music, 509-248-6015; and Speed Motor Sports, 509-453-7223.
