9 pm Friday, July 10., Friday July 10 | $10. Dante's 350 W Burnside St. [NEW ORLEANS MEDICINE SHOW] Imagine if Vagabond Opera had originated in N’awlins instead of Portland, and you’ll have an approximate idea of Dirty Bourbon River Show’s shtick. Channeling the pre-rock burlesque cabaret tradition, the band’s new album, Important Things Humans Should Know, flings gritty yet sometimes operatic vocals over a brew of sousaphone, keyboard, sax and accordion. It’s hard to imagine that a recipe of Balkan horns, old-time New Orleans jazz and vaguely punkish vocals could actually hang together, but just as with VO, the band’s vaudeville humor and showmanship makes its shows more than just another concert. Or as frontman Noah Adams says, “It’s like Shostakovich meets Entry of the Gladiators.”
