This Filisko song is a study in the "Box Shuffle." It is an instantly recognizable classic blues riff that is the same groove as the "Jimmy Reed" but tends to sound a little more modern. It should be an essential part of all harp players repertoire. While this version of the song is "bending light," it does not exploit the strengths of the harmonica and is full of rhythmical challengers and mainly uses notes from the blues scale. When you can perform the entire piece with attitude, you can move into the more difficult verson called "In the Box," which has more advanced bending in it.
