Audioslave

After Audioslave released three successful albums, received three Grammy nominations, and became the first American rock band to perform an open-air concert in Cuba, Cornell issued a statement in February 2007 announcing that he was permanently leaving the band "due to irresolvable personality conflicts as well as musical differences." The 2007 Rage Against the Machine reunion and tour involving three members as well as solo albums released that same year by Morello and Cornell cemented the supergroup's permanent demise. The band split up for a long period due to Chris Cornell and Tom Morello being busy recording and releasing solo albums, while the three remaining members were busy with the reunion of Rage Against the Machine. Audioslave reunited on January 20, 2017, to participate in Prophets of Rage 's Anti-Inaugural Ball to protest Donald Trump's presidential inauguration. However, they later disbanded again, this time for good. Further reunions were ultimately abandoned following Cornell's death in May of that year.
