In a matter of four short years, Led Zeppelin had delivered four groundbreaking albums each destined to top the other. Widely considered a hard rock, heavy metal band by many, Zeppelin would astonish everyone by creating one of hard rock's first epic ballads, the most played record in rock radio history, "Stairway To Heaven". Jimmy Page shares with host Redbeard the reaction the song got, even before Zeppelin had released it. "We were out touring and that album (Zep IV) hadn't come out and we played "Stairway" in the Forum (Los Angeles) and we got a standing ovation."

Jimmy Page and Robert Plant reveal In The Studio why Led Zeppelin IV is the third-highest seller in music history . "When we started the band...I wanted to make music that people would respect; your fellow musicians, like Jeff (Beck) and Eric (Clapton) and people like that ," remarks Page. Robert Plant remembers, "We did whatever we wanted to do and said, 'look, for us we have to just weave around wherever it was most appropriate, with amplifiers, without, doesn't matter, in the desert, on top a Welsh mountain wherever it was…' which could be indicative and could show what we were all about."
