Slide Boy Roy is a Blues Rock band from the UK and is also the (slide) guitar player from that band. And what I dig about the song is that it's both distinctly Blues and distinctly British Rock. To be honest, it sounds very much like something that could have been played by a band at the Cavern Club in the early 60s (not that band, but a band). If I've got any complaint at all, it's that it's too darn short. But I suppose all those early 60s songs were.
Other than that, I can't tell you too much about Slide Boy Roy. You can keep up with their doings on Facebook and listen to more of their music on Soundcloud. And boogie from now to Christmas day to the "Christmas Blues". Yeah, Baby, yeah.
