I just wanted to share a couple of this man's videos from YouTube. Kaoma Chende is a one man A Cappella Quartet. I think he's an amazing talent. He films himself separately singing the same song from four different positions and in different tones while being in the same room. Yes, he sings all four parts. I think he's too good not share at least a couple of these videos. You can find others on YouTube.

I Love You Lord
The Old Rugged Cross

He also has a few albums and a few singles on Spotify. https://open.spotify.com/artist/0pSdzKPTtVbySchxgcO9dh

I hope you enjoy it as much as I do.
