In a short video detailing how they operated during sessions the Rage Against The Machine drummer says: "I love their sense of humour. None of them take themselves too seriously." And he adds: "The guys are the best at what they do – it's inspiriting to be part of that."

In one scene Wilk is seen discussing one of the band's previous albums, of which bassist Geezer Butler tells him: "We spent more on the cocaine than we did on the studio."
