Here's Buddy Guy on David Letterman last night. Buddy - or, as Mick Jagger refers to him, Buddy Motherfucker Guy - is a living legend of the blues, and this is the title song from his new album, Skin Deep.
One of the Youtube commenters sez there's a little Sam Cooke in here - probably thinking of "A Change Is Gonna Come." And there is a little of Cooke's effortless smooth in Guy's vocal here - but there's also a lot of grit. And a little old San Francisco psychedelia - dig the sitar sound he's making with his guitar. But most of all this is just pure down deep spiritual wise song. It doesn't need classifying. Just listen.
This is the kind of music that can heal a nation. This is the kind of music that you can start a religion around.
