Fifteen years after its last album, in November 2008, Guns N' Roses released "Chinese Democracy" exclusively via the electronics retailer Best Buy. Rose did not contribute to the album's promotion; by December, he had reportedly been missing for at least two months and had not returned phone calls or other requests from his record label. In a subsequent interview, Rose said he felt he had not received the necessary support from Interscope Records. A year after the album's release, in December 2009, Guns N' Roses embarked on another two-and-a-half years of touring, including a headlining performance at Rock in Rio 4. Rose was subsequently sued by former band manager Irving Azoff, who sought $1.87 million in unpaid fees related to the tour. In a countersuit, Rose alleged Azoff had deliberately mismanaged the band and their album's promotion to force him to join his former bandmates for a reunion tour. Both cases were settled. According to Rose in 2011, part of the settlement agreement dictated that Rose and the current Guns N' Roses had to do a number of performances with Azoff's company Live Nation as the promoter.
