You don't have to go far at the Flamingo Las Vegas to remind Josh Huslig that a cappella isn't quite the coolest musical genre.
Huslig's sextet Mosaic is comedian George Wallace's opening act every night in the Flamingo's main showroom. In the same casino's cabaret venue, The Second City closes its nightly sketch-comedy show with a spoof of the vocal groups as most people know them, a theme park breed that runs neck-and-neck with Up With People on the peppy and perky scale.
"We're trying to reinvent it," Huslig says, comparing his group's efforts to the way Savion Glover put a cool face on tap dance, or Cirque du Soleil rehabilitated the circus.
