Query: Close to Heaven

Let me begin by saying that "Stairway to Heaven" is the most overplayed song in rock radio history. With that out of my system, let me also say that Led Zeppelin's fourth album is a classic that contains no bad songs and a lot of great ones. From the rocking opening cut "Black Dog" through the accoustic hippie musings of "Going to California" through the closing blues epic "When the Levee Breaks," this is great rock'n'roll. A triumphant album from a legendary band.
