Curiously, the 70s also gave us the Allman Brothers, Lynyrd Skynyrd, et al. Worlds are colliding!
And The Ramones, Black Sabbath, Sex Pistols, Led Zepplin, AC/DC, Scorpions, etc.... It seems to be very much a decade of opposites. Really horrid music (Carpenters, Disco, etc) and really good music too.
