Biko and Manna Nhlangothi are a sister and brother duo raised by musician parents that perform as Biko Manna. They’ve been dazzling crowds with their street performances in their home county of South Africa for several years but have recently hit it big by covering Japanese pop songs on YouTube.
Apparently the story is the father visited Japan and fell in love with Japanese pop music and brought back some music with him. His kids picked up the lyrics by ear and they’ve made their own cover versions.
I’d love to learn more about them, there’s very little written in English but I could see them touring Japan someday. Biko’s voice will knock your socks off but her brother and younger (friend?) that joins in to ham it up are a kick too.
Here’s a documentary I found that talks a little about their background.
If you want more Biko’s Manna, here’s a good playlist.
