mysteryguitarman performing epic edit choir
Shades-wearing YouTube star MysteryGuitarMan, aka Joe Penna, is hovering just outside the top 10 most subscribed YouTubers of all time. And for good reason! His latest video is an epic a cappella choir, performed solo and edited together with an impressive 897 cuts.

The Epic Edit Choir is just 2 minutes long, but it took 2 days to produce. It's already racked up a quarter of a million views in a single day. The song he's performing is 'O Fortuna,' from Carl Orff's Carmina Burana. You may also know it as "that bum bum bum bum song."

A cappella multitrack performances are nothing new on YouTube, of course, although this one is particularly good. A while back, we rounded up a few of the best.

We've also featured MysteryGuitarMan before: last time, he was playing Mozart on root beer bottles.
