When politically minded rap-rockers Rage Against the Machine split in 2000, the members quickly reunited sans vocalist Zack de la Rocha for a new project mashing their alt-rock leanings with Zeppelin-esque guitar rock. In a serendipitous turn of events, fellow ‘90s powerhouse Soundgarden had recently splintered as well, freeing up frontman Chris Cornell. Audioslave was a short-lived success, but a success nonetheless, notching three top 10 albums and several rock hits before collapsing in 2007. Both Soundgarden and Rage Against the Machine have since reunited.—Jeff Royer
