I want to know the answer to the following question:
What hard rock supergroup contained members of Soundgarden and Rage Against the Machine?
All the background I'm provided with is that "The long awaited Guns N' Roses album Chinese Democracy was finally released in 2008, but only went platinum and failed to come close to the success of the band's late 1980s and early 1990s material.". Is that enough to answer the question?
Answer: no
