I was there! I went to this concert when I was still a teenager living in Cuba and it was amazing! It was the first time an American rock band would perform in Cuba after 50 years. A lot of people were confused because they were not sure if it was "Soundgarden" or "Rage Against the Machine" the band that would perform, but still they went and had the time of their lives. I remember Chris Cornell and the rest of the band surprised to see that so many people knew the lyrics and were singing along. It was the first time Audioslave would play "Be yourself" live and other songs from their second album "Out of Exile." There was incredibly good energy that day and the documentary shows that. Not every day you get over 70,000 people attending a rock concert. One of the best concerts I've ever been to.
