This is by far my favorite song by the Derek Trucks Band. Derek Trucks is not only a successful solo artist, he was also one of Eric Clapton's guitarists at my concert. He was also in The Allman Brothers Band when he was only 15 years old, the guy has a seriously good resumé behind him. This album won a Grammy for Best Contemporary Blues album, and you can see why, Derek's slide guitar-style of playing regula guitar is absolutely incredible.
Fun fact: the other guitarist besides Clapton was the guitarist named Doyle Bramhall II, the son of the successful Blues guitarist by the same name. Doyle Jr. appears on this album with Derek Trucks, and helped compose several of the songs. They must have liked eachother from the Clapton tour. :)
