Pentatonix (abbreviated PTX) is a five-member American a cappella group from Arlington, Texas, with vocalists Avi Kaplan, Scott Hoying, Kirstin Maldonado, Kevin Olusola, and Mitch Grassi.
The group is noted for their medley-form song covers along with their original material. Their music typically features pop-style arrangements with vocal harmonies, basslines, riffing, percussion and beatboxing.
Pentatonix formed in 2011, rising to prominence that same year with its win of the third season of NBC's The Sing-Off, also receiving $200,000 and a recording contract with Sony Music. After being dropped from Epic after The Sing-Off, the group formed its popular YouTube channel and distributed its music through Madison Gate Records, a small label owned by Sony Pictures that mainly distributes movie soundtracks. The group uses social media to interact with its followers.
With over 11.5 million subscribers and 1.80 billion views, Pentatonix's YouTube channel is currently the 13th most subscribed music video channel and the 44th most subscribed channel overall. The group's most viewed music video is a tribute to Daft Punk with over 210 million views.
Their debut EP PTX, Volume 1 was released in 2012, followed by their holiday release PTXmas the same year, with Pentatonix's third release, PTX, Vol. II, debuting at number 1 on Billboard's Independent Albums chart and number 10 on the Billboard 200 in 2013. In May 2014, Pentatonix signed with RCA Records, a "flagship" label of Sony Music Entertainment, while in the same year, the group released their fourth EP, PTX, Vol. III, and two full-length studio albums; PTX, Vols. 1 & 2, a compilation album released in Japan, Korea and Australia, and their second holiday release, That's Christmas to Me, with the album certified gold by the Recording Industry Association of America (RIAA), platinum on December 24, 2014, and double platinum on February 11, 2016, becoming the highest-charting holiday album by a group since 1962, and the fourth-best-selling album in the United States in 2014. The following year, Pentatonix released their eponymous album, their first consisting mostly of original material, which debuted atop the US Billboard 200 chart for the first time in their career, followed by a third Christmas album, A Pentatonix Christmas, in 2016.
Pentatonix, together with music producer and arranger Ben Bram, won the Grammy Award for Best Arrangement, Instrumental or A Cappella twice, first in 2015 for "Daft Punk" at the 57th Grammy Awards, and then again in 2016 for "Dance of the Sugar Plum Fairy" at the 58th Grammy Awards; they are the only a capella artist to have won the award.
