Dave Alvin and Jimmie Dale Gilmore

Dave Alvin and Jimmie Dale Gilmore

A Blaster (read rocker) and a Flatlander (country-folk) doesn’t sound like a recipe for a duo. But high-energy Dave Alvin is an all-purpose Americana guy and gentle Jimmie Dale Gilmore actually can rock.

Hence, the Alvin/Gilmore duo turned out to be a roots-rockin’ treat on Thursday night at the Dakota Jazz Club.

Friends for 30-some years, Alvin from Downey, Calif., and Gilmore from Lubbock, Texas, toured as a duo last year (including an October gig at the Cedar Cultural Center), and this year they delivered a duo album, “Downey to Lubbock.”

This time, they’re on the road with Alvin’s band, the Guilty Ones, and that translated into a rockin’ good time, with some of Gilmore’s hippie folk material mixed in – like a spirited cover of the Youngbloods’ “Get Together,” a timely treatment of Woody Guthrie’s “Deportee (Plane Wreck at Los Gatos)” and Gilmore’s own “Tonight I Think I’m Gonna Go Downtown.”

But mostly the duo rocked for 100 minutes, whether it was on Alvin-penned gems like “Fourth of July” and the Blasters’ “Marie Marie” or a cover of Lloyd Price’s 1952 classic “Lawdy Miss Clawdy” (with Gilmore as a convincing R&B shouter) or Gilmore’s “Dallas” featuring Alvin’s smokin’ guitar.

One non-rockin’ highlight was the true duet “Billy the Kid and Geronimo,” one of two originals on the new album, in which Alvin sang the part of Billy and Gilmore Geronimo.

Great band, great songs, great spirit, some good humor. It added up to a blast.

Adding to the festivities was unadvertised opening act Jon Langford, a chatty Welshman full of energy and clever lyrics who came across like a hybrid of Joe Strummer and Elvis Costello. And Langford, a veteran of the Mekons and Waco Brothers, is a gifted painter, too – he created the cover of Alvin and Gilmore’s “Downey to Lubbock” album.
