The Social Network trailer shone a spotlight on the unique musical project that is Scala & Kolacny Brothers ­ an indie-rock choir, comprising of the two Kolacny brothers, Steven and Stijn, and Scala, their all-girl choir. Steven plays the piano, Stijn conducts the choir. The brothers usually work with 15-30 singers, aged 16-28, at a time, but these days have more than 200 girls on their books, ensuring plenty of cover for their increasingly busy schedule.

Scala & Kolacny Brothers take rock and indie songs and reinvent them as elegiac hymns ­ to breathtaking effect ­ with the piano often the sole accompaniment to the voices. On occasion they also use drum machines, sequencers and synthesizers, and also often perform with a full rock band.
