Among the events that might get lost amid the many happenings in the rock bars of Columbus this weekend: the reappearance of two bands that used to be prominent players in those bars.

Among the events that might get lost amid the many happenings in the rock bars of Columbus this weekend: the reappearance of two bands that used to be prominent players in those bars.

Paper Airplane hasn’t performed since drummer Antonio Garza moved to California for law school last year. Loyal Divide, on the other hand, has been playing a lot, including gigs with Chromeo and Crystal Castles; the former Columbus combo spent the past four years building a buzz in Chicago and around the internet. Both bands will be back in action locally this weekend to celebrate the release of new albums.

For Paper Airplane, the show is a temporary reunion to give last year’s “Who You Know” its proper due. The band’s third album is yet another set of expertly assembled pop songs with melodies that stick and vocal harmonies to spare. Released on the local We Want Action label, it’s exactly the kind of album you’d expect (and hope for) from Paper Airplane.

Garza left town last fall before “Who You Know” could be released. He’ll be back for the weekend, so the band is playing one last concert at The Summit this Saturday to commemorate a record that represents a fine cap on a consistently rewarding career. The Japanese B-sides and Bookmobile — another reunited Garza band — will open.

Loyal Divide’s show Friday at Ace of Cups will be more forward-looking. Since skipping town they’ve veered their multi-hued anthems hard left into electro-pop, yielding tracks like the DJ Quik- and Pitchfork-approved half-time funk firebrand “Vision Vision” and “Young Blades,” an off-balance movie monster that sounds like Portishead covering The Beatles’ “Because.”

“Bodice Ripper,” released last week on Kilo Records, compiles their best work from more than four years of recording. This band has always been bursting with ideas; now they’ve transformed them into something powerful and focused. Their gig with The Town Monster and New City Gypsy should be a triumphant occasion.
