If the first Led Zeppelin album is the birth of heavy metal, then this one is stage two, fueled by the booster rockets of the first cut Whole Lotta Love. I forgot just how heavy this record was (still is) and it amazes me that it came out over 40 years ago. If you think back to then, Rock & Roll, “that loud music that the kids are listening to” was the White Album from the Beatles, or Crosby, Stills & Nash, or even The Doors/The Soft Parade. Compared to those albums, this must have sounded like an atomic bomb going off. And if it was played the way we played it in my basement 10 years later, it isn’t a wonder some ceiling tiles got busted, and some “good times, bad times” were had by all. I especially like the Tolkien reference on Ramble On.
