Are you familiar with futuristic a cappella quintet Pentatonix? If not, you should be — their unique arrangements and sharp vocal percussion can make any song sound aca-awesome. (For real — check out their take on “Carol of the Bells.”) While they’re skilled enough to perform in a multitude of styles, the Sing-Off winners are especially good when tackling beloved boy-band hits from the ’90s and early ’00s, which come with ready-made multipart harmonies.
Want proof? Check out this medley of classic ‘N Sync tunes, including “Pop,” “Tearin’ Up My Heart,” and “It’s Gonna Be Me.” Blond Scott Hoynig is a dead vocal ringer for JC Chasez; brunet Mitch Grassi’s tenor lends itself beautifully to a Justin Timberlake impression. Really, though, the whole thing is good enough to make you forget the original versions of these songs, at least for three minutes.
