I have long theorized that music in general works in cycles of twenty to twenty-five years, and that what's old can continually be made new again, like doctoring up that potato salad for one last go-around. To wit, in the 1990's, Pantera, Alice in Chains and the rest of grunge listed their influences as Led Zeppelin, Black Sabbath, Deep Purple and the classic rock of the 70's. In the 1970's, Led Zeppelin and their cohorts listed their influences as Chuck Berry, Blind Lemon Jefferson, and the blues and rock musicians of the 50's.
