Unschooled in the "neo-cabaret" musical genre? Don't fret - just check out Portland's Vagabond Opera - returning to Olympia this Saturday for a performance at the Olympia Ballroom that promises to be mesmerizing. Even more exciting: the show will act as a celebration of the Vagabond Opera's just-released fourth full-length record, as well as the release of local favorites Erev Rav's latest CD - with that band also on the bill. Truly offering music of the world, the six-piece Vagabond Opera reportedly dabbles in sounds spanning the globe - from European cabaret, to Balkan belly dance, to Old World Yiddish theater and beyond. There's a reason this mesmerizing troupe has shared stages with the Decemberists, Pink Martini and Al Franken and the Oregon Symphony. It's because they're awesome. - Matt Driscoll
