Passage: Madonna released and performed the song "Hey You" at the London Live Earth concert in July 2007. She announced her departure from Warner Bros. Records, and declared a new $120 million, ten-year 360 deal with Live Nation. In 2008, Madonna produced and wrote I Am Because We Are, a documentary on the problems faced by Malawians; it was directed by Nathan Rissman, who worked as Madonna's gardener. She also directed her first film, Filth and Wisdom. The plot of the film revolved around three friends and their aspirations. The Times said she had "done herself proud" while The Daily Telegraph described the film as "not an entirely unpromising first effort [but] Madonna would do well to hang on to her day job." On March 10, 2008, Madonna was inducted into the Rock and Roll Hall of Fame in her first year of eligibility. She did not sing at the ceremony but asked fellow Hall of Fame inductees and Michigan natives The Stooges to perform her songs "Burning Up" and "Ray of Light".Madonna released her eleventh studio album, Hard Candy, in April 2008. Containing R&B and urban pop influences, the songs on Hard Candy were autobiographical in nature and saw Madonna collaborating with Justin Timberlake, Timbaland, Pharrell Williams and Nate "Danja" Hills. The album debuted at number one in 37 countries and on the Billboard 200. Caryn Ganz from Rolling Stone complimented it as an "impressive taste of her upcoming tour", while BBC correspondent Mark Savage panned it as "an attempt to harness the urban market".
