Anton Zaslavski, known professionally as Zedd, is a German record producer and DJ. His stage name was derived from zed, the English pronunciation for the first letter of his surname. Raised in Kaiserslautern, Zedd rose to mainstream success with his 2012 single "Clarity", which peaked at number eight on the Billboard Hot 100 and won Best Dance Recording at the 56th Grammy Awards. It served as the third single for his debut studio album of the same name (2012), of which its deluxe edition spawned the US top 20 single "Stay the Night".

Pentatonix is an American a cappella group from Arlington, Texas, consisting of the vocalists Scott Hoying, Mitch Grassi, Kirstin Maldonado, Matt Sallee, and Kevin Olusola. Characterized by their pop-style arrangements with vocal harmonies, scat singing, riffing, vocal percussion, and beatboxing, they produce cover versions of modern pop works or Christmas songs, sometimes in the form of medleys, along with original material. Pentatonix was formed in 2011 and subsequently won the third season of NBC's The Sing-Off, receiving $200,000 and a recording contract with Sony Music. When Sony's Epic Records dropped the group after The Sing-Off, the group launched its YouTube channel, distributing its music through Madison Gate Records, a label owned by Sony Pictures.
