Recently, I have been playing in a local band that is , esentially, a Blues band. After mucho years of playing rock music, it is a refreshing change. Not to say I don't still love Classic Rock. Having cut my teeth on the Acid Rock standards like Hendricks and Cream along with the R & B classics, I never realized how many of the Rock hits were actually basterdized versions of Blues tunes. The bass lines are very recognizable even if the title isn't.
