Origins and the Pentatonix Original Members
When the group formed in 2011, the pentatonix original members included Scott Hoying, Kirstin Maldonado, Mitch Grassi, Kevin Olusola, and Avi Kaplan. This quintet met through a shared love of vocal arranging and a competitive YouTube environment that rewarded tight harmonies.
Their early videos, such as a now-famous Radioactive cover, showcased intricate layering without instruments. The original lineup established the blend of bass, tenor, alto, and soprano that defined Pentatonix in the a cappella boom.
Changes and Departures That Shifted the Lineup
