The five-member a cappella group, who rose to fame after winning the 2011 season of NBC's "The Sing-Off," just won the Grammy for Best Arrangement, Instrumental Or A Cappella for their "Daft Punk" medley. They share the award with arranger/producer Ben Bram.
"Oh my god, we just want to thank everyone who has helped us along the way," PTX's Scott Hoying told MTV red carpet correspondent and Archduke of YouTube Todrick Hall. "The fans, our parents, our manager, RCA -- it's pretty surreal."
In case you're not familiar, here's the video for the PTX, Vol. II hit, which mashes up Daft Punk tracks "Harder, Better, Faster, Stronger," "One More Time," "Get Lucky," "Digital Love" and "Television Rules The World."
Not to get all Leslie Carter, but like, wow -- no wonder they won for this arrangement.
