When the average citizen thinks of jam bands, names like Phish and Widespread Panic come to mind. But Led Zeppelin jammed too, and Stone Sugar Shakedown's blues-steeped explorations tend to resemble the latter. The band sounds and looks transplanted from the 1970s, with hints of the Blues Brothers and Funkadelic, and it doesn't hurt that singer Tracy Gladden can alternately channel Grace Slick and Roberta Flack. It is no surprise that Stone Sugar Shakedown is incredibly active with appearances at clubs and festivals throughout the Midwest. The band is a crowd pleaser; it is sometimes funky, sometimes psychedelic, but it always infuses its tunes with an energy that only true believers in the power of rock can embody.
