Pentatonix is best known for being the latest winners of the now-cancelled NBC show The Sing Off. On the show, they were praised for being able to reinvigorate popular songs with their unique sound, which includes only 5 members and no instrumentals. Since winning the show, the acapella group has been hard at work on their upcoming EP, as well as uploading covers to their YouTube channel.
Their latest upload is a mash-up of Top 40 hits Wide Awake by Katy Perry and As Long As You Love Me by Justin Bieber. This video will surely spread across the web like wildfire, since essentially the band is not only talented, but add an extra level of novelty with their lack of musical accompaniment.
