Watch Duo Perform Epic Cover of Beyonce's Fifth Album

Mitch Grassi and Scott Hoying, two-fifths of the a cappella sensation Pentatonix, take on Bey's surprise album in an epic YouTube video cover. While Pentatonix is known for its instrument-less takes on everyone from Mrs. Carter to Daft Punk, Hoying and Grassi mix it up with some piano to create a stripped down version of "Drunk in Love," "XO" and the rest of the album's 'flawless' tracks.

Watch as Hoying and Grassi aka Superfruit get their Bey on. It's worth watching through to the end when they flow from "Heaven" into "Blue" and beautifully mix in "XO."
