Video: Pentatonix feat. Tink - 'Can't Sleep Love'

Here’s something you didn’t see coming—Chicago rapper, singer, and Timbaland protégée Tink has teamed up with none other than Pentatonix, the a cappella group who came to fame through vocal arrangements of pop songs. Recently, though, Pentatonix has branched out into recording original material, like “Can’t Sleep Love.”

Using only their voices, they create a sensual R&B groove with a late ’90s neo-soul vibe. Tink comes in for a brief but punchy guest verse, calling herself “hot as a volcano” in her poised, syrupy voice. Good luck getting this one out of your head.

Look for the song on Pentatonix’s self-titled album (due Oct. 16), which also features their cover of OMI’s “Cheerleader” and the Jason Derulo-assisted “If I Ever Fall in Love.”
