Very little is known about Charlie Brown, born in Columbus, Georgia and died in Brooklyn, New York 1994. He was a session musician in the sixties and seventies and made two own records, this one and "Portrait Of A Glad Man" 1970 (wich I never heard, but it would be very cool to do). The information on discogs.com says he backed artists such as Van Morrison, Solomon Burke, Coasters and Barbara Lewis. Allmusic tells James Brown, Esther Phillips, Idris Muhammad, Loudon Wainwright and Bob Dylan (Blood On The Tracks). I don't know if it's correctly, but it sounds cool.
The music on this LP from 1972 is a very groovy country tinged swamp rock affair, sometimes very guitar driven. If you ask me several of the songs from the album could have been appeared on the two compilations "Country Funk" for example.
