In 1973 the seminal rock band Led Zeppelin, one of the founders of the music genre known as "heavy metal," went on tour and performed in Madison Square Garden. This documentary has concert footage, including the 23-minute-long version of the song "Dazed and Confused." The film also shows the musicians at home, pursuing some of their hobbies including drag-racing. The concert coverage also has scenes revealing what took place backstage, and a discussion of the theft of the band's cash during their visit to New York. ~ Clarke Fountain, All Movie Guide
