With classics like Whole Lotta Love, Heartbreaker, Ramble On, and Moby Dick, Led Zeppelin's second album is widely considered to be one of the band's best and Rolling Stone is calling it one of the best sophomore albums of all time.

In Rolling Stone interview, guitarist/producer Jimmy Page recalled the insanity of the recording process and says that it's where the band's identity really came together.  Page remembers:

"We had no time, and we had to write numbers in hotel rooms. By the time the album came out, I was really fed up with it. I'd just heard it so many times in so many places. I really think I had lost confidence in it."

In the United States alone, Led Zeppelin II has sold over 12 million copies.  It routinely ranks among critics' best albums of all time.

The album was thrown together.  Drummer John Bonham recorded the percussion parts to Ramble On on either a guitar case, drum stool, or garbage can.  Nobody remembers which one.  Page forced the band to return to the studio immediately following a reception for the success of the band's debut album.
