The Siegel-Schwall Band

One of the '60s blues groups who may not have made a very large impact on blues, but their devotion to it certainly brought many fans to the genre. Not as furious as some of the more well-known acts of the genre, this group focused more on acoustic instruments and a collective mentality (though they were just as proficient plugged in). The group continued to record up through the mid-1970s, with a brief reunion staged in the late '80s.
