This YouTube video features my favorite a cappella jazz choir from Slovenia. If that sounds strange, you obviously didn’t watch this Video of the Day. Check it out, and you’ll become an instant fan.

In this video, Perpetuum Jazzile mixes a handful of Bee Gees tunes. It’s a heavy shot of disco nostalgia. And the group pulls it off flawlessly. Again, this reinvention rivals the original versions.

This group has some seriously talented singers. But don’t forget about the beatboxer. He’s the group’s drummer. Only he doesn’t use drums. He lays down the beat with his mouth. Watch for him. You’ll be impressed.
