The stark piano chords and subtle-yet-piercing vocal approach Christina Aguilera and A Great Big World created on "Say Something" made it a multi-platinum Top 5 hit. But Pentatonix—arguably America's favorite a capella group with a Top 10 album and a hit single from this holiday season—have somehow made the ballad even more emotionally jarring with a new cover.
"Say Something" is now a lush, five-part arrangement with layers of harmonies and subtle beatboxing. PTX's sole female member Kirstie Maldonado takes lead on the majority of the song, busting out big-time belts Xtina herself would be proud of. And you'll get chills when you hear Avi Kaplan (in the beanie) on the bridge section.
Although Pentatonix are an a cappella quintet, they added a special twist to this cover: A cello. Beatboxer Kevin Olusola multitasks by spitting the beat and playing cello during "Say Something."
Pentatonix's covers essentially go viral the moment they post to YouTube—a cover of Jessie Ware and Sampha's "Valentine" posted 15 days ago has 1.1 million views—but we're wondering if this could be their biggest yet. In less than 24 hours, the cover has earned nearly 600,000 views. The original "Say Something" is currently at No. 4 in its 15th week on the chart, so people are digging the song already. And after PTX cracked into mainstream consciousness with their "Little Drummer Boy" cover, we think this could be their hugest viral hit yet.
