7. Three Hours of Led Zeppelin

At The Bath Festival in Somerset, England in 1970, Led Zeppelin etched their name as one of music’s all-time greatest legends. In their 3-hour, 5-encore set, the band played the anthemic Immigrant Song for the first time. It was one of Led Zep’s best and most important performances, and one of music’s most memorable milestones.
