Pentatonix is an a cappella group who gained notoriety after winning Season 3 of NBC’s The Sing Off, a competition for a cappella bands. The group consists of members Mitch Grassi, Scott Hoying, Kirstin Maldonado, Kevin Olusola, and Matt Sallee, who replaced original member Avi Kaplan. Kaplan announced his departure from the group in May 2017.

PTX has made history as the first a cappella act to win the Grammy for Best Arrangement, Instrumental, or A Cappella — they won the award in both 2015 and 2016. They also won Best Country Duo/Group Performance in 2017 for their collaboration with Dolly Parton.

The group released their self-titled debut studio album in 2015, consisting of mostly original songs. The album was certified gold in February 2016 and debuted on top of the Billboard 200, spending thirty weeks on the chart.

Aside from their studio albums and covers, the band is known for their musical presence during the holidays. Their 2014 holiday album That’s Christmas To Me is certified double-platinum, their 2016 holiday album A Pentatonix Christmas is certified platinum and reached the top of the Billboard 200. The group has received multiple RIAA certifications for multi-platinum, platinum and gold-selling albums and singles, a Daytime Emmy nomination, starred in three holiday specials on NBC and appeared in the feature film Pitch Perfect 2. In 2019, Pentatonix released a compilation of their biggest holiday songs, The Best of Pentatonix Christmas, which included their multi-platinum singles “Hallelujah” and “Mary, Did You Know?” and collaborations with Kelly Clarkson, Maren Morris, Jennifer Hudson, Tori Kelly, Jazmine Sullivan and a duet featuring Whitney Houston.

Pentatonix released their At Home EP along with original music videos for their “Home” medley as well as for their covers of “Blinding Lights” (The Weeknd), “when the party’s over” (Billie Eilish), “Break My Heart” (Dua Lipa) and “Dreams” (The Cranberries) in June 2020.

Most recently, the band released their first original song in five years, a single called “Happy Now” along with an official music video.
