Meaning: The quote by Robert Plant, the legendary lead singer of the iconic rock band Led Zeppelin, provides insight into the band's rapid rise to fame and the impact of their live performances during their initial U.S. tour. Plant's reflection on this pivotal moment offers a glimpse into the band's early experiences and the profound impact they had on audiences and fellow musicians.

Led Zeppelin's first U.S. tour took place in 1968, shortly after the release of their debut album. The band, consisting of Robert Plant, Jimmy Page, John Paul Jones, and John Bonham, embarked on this tour with a relatively low profile, as they were still establishing themselves in the music industry. The tour marked the beginning of their foray into the American music scene, and it turned out to be a defining period for the band's trajectory.

Plant's realization about what Led Zeppelin was about likely refers to the transformative effect of their live performances on both the band members and the audience. As they traversed the country, their electrifying shows and musical prowess began to garner attention and acclaim. The quote suggests that the band's impact on audiences and their fellow musicians became increasingly evident as the tour progressed.

The mention of starting off "not even on the bill in Denver" underscores the humble beginnings of the tour, where Led Zeppelin may have been relegated to a lower position on the lineup or added as a last-minute addition. This experience speaks to the challenges and uncertainties that often accompany a band's early career, as they strive to gain recognition and make their mark in the competitive music industry.

The progression from being "not even on the bill" in Denver to reaching a point where they were "second to Iron Butterfly" in New York highlights the rapid ascent of Led Zeppelin's popularity and influence. Iron Butterfly, a prominent band at the time, was known for their hit song "In-A-Gadda-Da-Vida" and was a significant act in the rock music scene. The fact that Led Zeppelin rose to such prominence within the span of a single tour is a testament to the magnetic allure of their music and performances.

The revelation that Iron Butterfly "didn't want to go on" when Led Zeppelin was scheduled to perform next underscores the profound impact that Led Zeppelin had on their fellow musicians and the dynamics within the music industry at that time. It suggests that Led Zeppelin's live performances were so commanding and captivating that they posed a formidable challenge for the act that followed them. This anecdote provides a powerful testament to the band's ability to captivate and enthrall audiences and fellow musicians alike.

In conclusion, Robert Plant's quote encapsulates a crucial moment in Led Zeppelin's early career, where their live performances during the first U.S. tour propelled them to newfound levels of recognition and influence. The quote serves as a reminder of the band's meteoric rise and the indelible impact they had on the music landscape, setting the stage for their enduring legacy as one of the greatest rock bands of all time.
