Please answer the following question: Given the following context:  On March 19, 2002, Audioslave was confirmed for the seventh annual Ozzfest; despite, at that time, having neither an official name nor a release date for their debut album. A few days later, reports surfaced that the band had broken up before they had played for a public audience. Cornell's manager confirmed that the frontman had left the band, with no explanation given.Initial rumors suggested that Cornell took issue with having two managers actively involved in the project (Jim Guerinot of Rebel Waltz represented Cornell, and Peter Mensch of Q Prime handled Rage Against the Machine). According to the band, however, the split was not triggered by personal conflicts, but by their quarreling managers. After the mixing of the album was finished, roughly six weeks later, the group reformed and simultaneously fired their former management companies and hired another, The Firm. Their previous labels, Epic and Interscope, settled their differences by agreeing to alternate who released the band's albums.Meanwhile, 13 rough mixes of songs the band had created months previously were leaked to peer-to-peer filesharing networks in May 2002, under the name "Civilian" (or "The Civilian Project"). According to Morello, the songs were unfinished and, in some cases, "weren't even the same lyrics, guitar solos, performances of any kind." To MTV, he described them as "inferior sketches of works-in-progress, sent to Seattle for Chris to work on. Someone at that studio helped themselves to a copy and, after eight months, it made its way to an Italian website. Then it went global and everyone thought they had the record, which was so frustrating."  answer the following question:  What band's frontman left?
A:
Audioslave
