Pentatonix (abbreviated PTX) is an American a cappella group from Arlington, Texas, currently consisting of vocalists Mitch Grassi, Scott Hoying, Kirstin Maldonado, Kevin Olusola, and Matt Sallee. Characterized by their pop-style arrangements with vocal harmonies, basslines, riffing, 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 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 formed its YouTube channel, distributing its music through Madison Gate Records, a label owned by Sony Pictures. Their YouTube channel currently has 20 million subscribers and 5.9 billion views. The group’s video tribute to Daft Punk has over 365 million views as of December 29th, 2022.
