February 7. Thanks to YouTube, Postmodern Jukebox, the New York orchestra headed by arranger and pianist Scott Bradlee, has become a certified sensation and here headlines the Bardavon. The amorphous ensemble emerged out of Bradlee's previous project, an outfit that recorded 2011's A Motown Tribute to Nickelback (?!), and won the viral admiration of millions (sometime local author Neil Gaiman among them) for its prewar jazz and ragtime reworkings of contemporary pop hits by the likes of Miley Cyrus, Guns 'N Roses, the Strokes, Katy Perry, Radiohead, and Lady Gaga. In 2013, the phenomenon hit new heights with the release of the group's debut, Introducing Postmodern Jukebox, which made the Top 10 of Billboard jazz albums chart. 8pm. $48-$68. Poughkeepsie.
