The midname slash suggests division, each element safe on its side of a semantic or sonic partition. And the maelstrom of Brooklyn’s Akron/Family may indeed be segmented, but it all still manages to flow with the grace of a caterpillar. Bare-room balladry gives way to hand claps, a ramshackle choir, and a scattering of bleeps; guitar spirals get undone by kitchen-cupboard cacophony and a colonnade of melting synths. Tonight, A/F is in town to support its second record of 2005 after a splendid self-titled debut this spring. That the recently released split EP with the group’s label boss, producer, and Svengali, Michael Gira (aka Angels of Light), may -actually count as A/F’s third CD this year—the band also backed Gira on The Angels of Light Sing ‘Other People’—cements its status as heir apparent to the twiggy throne vacated by Gira’s young god of the last few years, Devendra Banhart. But with its smooth contours and big-eyed song cycles, it seems as if A/F is leapfrogging over warbly DB and the pastures of New Weird America to ascend to the same art-rock orbit as Sigur Rós and other present-day prog-geny. Akron/Family plays with Kitty Hawk at 9 p.m. Thursday, Dec. 8, at Iota Club and Cafe, 2832 Wilson Boulevard, Arlington. $10. (703) 522-8340.
