Pentatonix Through the Years [Gallery]
From the first time we saw them perform on — and eventually win — the third season of NBC's The Sing-Off, Pentatonix have graced everyone with their beautiful voices and perfect harmonies. There's also the fact that they have taken a cappella to another level with using their classical vocal techniques to turn Daft Punk and Beyoncé songs into medleys that have garnered millions of views.
Aside from gaining star status, they've won three Grammy Awards and released five full-length albums, plus two holiday records that have done very well on the Billboard charts.
We took look back on the pop singing quintet's career thus far and picked out their biggest red carpet moments, as well as their style's evolution over time. Scroll through the gallery above.
