Belgian Choir Puts Ethereal Spin On Kings Of Leon, U2

Many Americans first heard of Scala and Kolacny Brothers when the trailer to "The Social Network" featured the group's ethereal all-vocal version of Radiohead's "Creep."

The group has now released a self-titled U.S. debut album, featuring covers of Nirvana, Kings of Leon and U2 as well as original work.

We speak Scala conductor Stein Kolacny and his brother Steven Kolacny, who is the arranger, composer and pianist.
