A few years back, I came across this beautiful song titled Ihunanya from his A Perfect Progression album. It was written and performed by Kelechi Ify.
Recently, I discovered this other song. It's a hymn, which may or may not be familiar to you: Be thou my vision. Tolu plays the piano throughout. I guess that means you can sing or hum along. Turn it into karaoke if you like :-)
It's one of the few instrumentals featured on this blog, but I hope you find it as calming and peaceful as I did. Plus, it's free. Enjoy!
