Garage-rock bashers The Clutters have been a fixture within the local rock scene for the better part of a decade — not to mention a candidate for Best Local Band Name, what with “The Clutters” being a pretty solid true-crime/Truman Capote reference and all. With bassist Jake Rosswog traveling internationally as assistant tour manager for Morrissey’s current tour, however, it seems The Clutters are out of commission until this summer. But, not content to twiddle their thumbs for several months, frontman Doug Lehmann and drummer Stephanie Brush formed a splinter group by the name of Mystery Twins. Their forthcoming EP — titled Love Is Strange, in honor of their cover of Mickey and Sylvia’s 1956 hit of the same name (anybody else remember that scene in Terrence Malick’s Badlands?) — won’t be out for another month or two. But live, the duo has already begun to hone their minimalist chemistry, harmonizing, thumping and loud-quiet-louding their way through first-generation R&B and rock ’n’ roll tunes (Petula Clark’s “Heart” is a standout) and originals alike. Tonight, the Twins are sandwiched amid a solid local-rock slew, including Nashville’s reigning jokester shreditor-in-chief Ri¢hie, power-poppy East Side rockers Century Club and relative newcomers Ohio Knife.
