After a year off, The Sing-Off returns for a fourth season to NBC this Christmas. Season 3 winners Pentatonix have gradually become the singing competition’s Kelly Clarkson by being the most successful out of the bunch. Since winning two years ago, their debut EP debuted at No. 14 with a brand new one dropping this week. In addition, they’ve appeared in numerous YouTube videos which have gone viral.
One of their best is the epic “Evolution of Beyoncé” which chronicled the “Irreplaceable” singer’s discography all the way from her Destiny’s Child days to her “Grown Woman” era. Their a capella medley was genius. Apparently, Ellen Degeneres thought so too. She brought them on her show Monday to perform it for a live studio audience. Not surprisingly, it’s pitch perfect. Check it out below, along with the original and their interpretation of the evolution of music. That’s brilliant as well.
