Beat-Bach-sing: beatboxing to Bach Xeni Jardin 6:52 am Thu, Dec 13, 2012 Teenage pianist/software developer/Apple enthusiast Kadar Qian (Twitter) teams up with 23yo “beatbox cellist” Kevin “K.O.” Olusola of Pentatonix (as featured on NBC’s “Sing Off“) to reinvent the Goldberg Variations, a work for harpsichord from 1741 by Johannes Sebastian Bach. The video is by From the Top, a nonprofit org in Boston that supports talented young musicians. (thanks, Joe Sabia!)
