Charles, along with his Menahan Street Band play vintage soul here on his debut album. Daptone Records picked him up after hearing his James Brown tribute shows at a bar near the label. Charles had been janitoring in the label's basement for years. Touring with the likes of Lee Fields (whose style is pretty similar) he represents the modern soul/funk scene that tries to emulate the sound of the 60s/70s "golden" period of the music.
It's a solid collection of tunes ranging from James Brown gut-punch funk tracks to slowed down, dreamy ballads, and the album as a whole captures such a vintage sound. Check out NPR Music's recent program on the man for some further stories, news, etc. Find the album in the comments.
