Led Zeppelin, "Stairway to Heaven" (1971)
FM radio in the Seventies celebrated music of great length, great breadth and great depth – even if sometimes maybe the audience had to be just a little bit stoned to find it deep. And no band commanded those airwaves quite like Led Zeppelin. "Stairway" is long – eight minutes and two seconds. "Stairway" is broad – as the song builds, the pastoral mysticism of Zeppelin's Ren Faire folk side evolves into the thunderously dexterous bludgeon that made them metal heroes. For sure, Zeppelin could and did get heavier and wilder than "Stairway." But they never got Zeppelin-er.
