Pentatonix – Can’t Sleep Love ft. Tink

Unexpected collaboration alert!

Season three winners of NBC’s “Sing-Off,” Pentatonix, link up with Timbaland’s newest Chicago protégé Tink for “Can’t Sleep Love.”

As always, the a capella quartet slays their vocal instrumentation — this song in particular has a smooth R&B groove with a hint of even more smooth flow by Tink. The video has the group members surrounded by colorful contortionists.

Pentatonix’s self-titled album is due out on Oct. 16. Pre-order above!
