Some may qualify the zany musical productions of the Jay Purdy-led Extraordinaires as quirky; however, sometimes creativity doesn’t mold itself into a common shape. Rather than attempting to forcefully place The Extraordinaires into the confines of genre, Purdy and crew focus their creative energies into developing music which is hinged on sound fundamentals – interesting narrative-driven lyrics matted on tight instrumental backdrops. These musical snapshots may change their focus at unexpected times, but the quality remains spot on. Join them tonight at KFN with the soulfully funky twang of You Do You, the punk-rock specialties of Business Model featuring Peter Helmis (of the recently departed Algernon Cadwallader), and electronic outfit Math the Band. Kung Fu Necktie, 1250 N. Front St., 7:30pm, $8, 21+ – Michael Colavita
