Last week nearly an hour of previously unseen live footage of Led Zeppelin performing live in Montreal in 1975 appeared online. Now the same source has delivered another 25 minutes of film, this time from a controversial Led Zeppelin show two years later in Chicago.
The footage comes from the third night of four Zeppelin played at the 18,000-capacity Chicago Stadium in early April 1977. The band had based themselves in the city for the North American tour, flying out to shows in other cities and returning "home" after.
