Charlie Harris and his band KEEP GUESSING CHARLIE come out of Johannesburg, South Africa, mixing folk-rock grit with straight-up rock and a touch of grunge. Fans often hear echoes of R.E.M., Nirvana, Golden Earring’s The Naked Truth, and Seasick Steve in their sound.

With two albums, an EP, and a stack of singles already released, they’ve earned the tongue-in-cheek title: “the best garage band you don’t know.” And with more singles and videos on the way, they’re only getting louder on radio—and harder to ignore.
