This signature Austin act possesses a campy hootenanny spirit as infectious as it is irreverent. They’re like the Squirrel Nut Zippers’ bawdy, whimsical, dope-smoking, pop culture-loving kin, parlaying their love of early acoustic jazz/blues/country and fun-loving theatricality into a 16-year career. While fine players with obvious appreciation for old-time string bands, it’s their penchant for canny covers that’s perhaps attracted the most attention. From their Hee Haw-style “TV Party” hoedown to “Tight Like That,” which crashes the Tampa Red classic into Jim Carroll’s “People Who Died,” and their Tony Orlando & Dawn-biting anti-war anthem, “Stick Magnetic Ribbons on Your S.U.V.,” the reinventions epitomize their playful attitude. But that’s hardly their limit. They’ve got fine originals, including the Tin Pan Alley acid ode “Trippin’ Over You,” the ambling country “My Baby In The CIA” and the gangsta-inflected murder ballad “Hick Hop.” Yuk it up on what’s billed as their farewell tour.
