Pentatonix

Pentatonix (abbreviated PTX ) 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.
