What an amazing record. Hard to believe it wasn't a hit.
Jody Williams plays guitar on this one, as he did on a number of totally brilliant sides by Bo Diddley, Howlin' Wolf, Otis Rush, and a bunch of others. The short-lived Cobra label was owned by Eli Toscano, but Willie Dixon was the man responsible for the label's sound. One fabulous 45 after another, 33 releases in only three years.
If you need more info on Harold Burrage, you can find it here. Unfortunately it's only the standard poop from All Music, oddly enough I couldn't find much more.
[Btw, there's a very nice comp of Harold Burrage sides around titled, "Messed Up". Ya'll should check it out, if you haven't already.]
