If you haven't heard of Pentatonix in the past couple of years, where have you been? The a cappella group has become an international sensation with their pop-style arrangements of classics and their spine-tingling harmonies.
The group has sold more than 6.4 million albums in the United States alone. They have also won three Grammy awards, and have been nominated for a Daytime Emmy. The group had its first big break when they won the reality show, The Sing-Off, in 2011. They won $200,000 and a recording contract with Sony, but they were dropped almost immediately after.
After they were dropped, the group started up their YouTube channel and gained over 2.7 billion views. Their music began getting distributed through Madison Gate Records, and in 2012 their first EP was released.
The original members were Scott Hoying, Mitch Grassi, Kirstin Maldonado, Kevin Olusola, and Avi Kaplan. They really shot to fame after covering Dolly Parton's Jolene, with Dolly herself. But after years of service to the group, Avi decided to leave. Fans were left broken-hearted, wondering who would replace the vocal bass and percussion hole.
After about six months of speculating, Pentatonix finally revealed their new member, and they did it with a new cover of a Christmas classic.
