Pentatonix is the fourth studio album by American a cappella group Pentatonix, which was released on October 16, 2015. The release date was announced on Twitter by a series of pictures featuring the five band members released over a five-day-span, with one band member added to the picture each day, culminating in the date being revealed on August 28. It is the group's seventh release overall in their discography. This is the first release of the band to feature predominantly original material (the only covers being the cover of Shai's "If I Ever Fall in Love" and the bonus tracks on the deluxe version of the album). Pentatonix also marks the first time band members receive individual songwriting credits for the majority of the tracks. Pentatonix debuted atop the US Billboard 200 chart with 98,000 album-equivalent units, with the album being their first No. 1 album on the chart.
