Impromptu brings back its "extreme a cappella" to the Duke Energy Theater performing all those songs that we secretly love but hate to admit it! You know, the ones that you have hidden in your iPod or iPhone and can't help listening to whenever they pop up on shuffle! Who can forget classics like "I Wanna Dance with Somebody" or "Girl from Ipanema?" Who doesn't belt out "Wake Me Up Before You Go Go" whenever they hear it? Impromptu is also excited to present the premiere of Deke Sharon's hot new arrangement of "Love Shack." Yep, there will be dancin' and clappin' in the aisles -- we love (and encourage) audience participation!
