Scream, Chris Cornell’s full-length collaboration with Timbaland, came out this week, and, as you might expect, the reception hasn’t been so great: the L.A. Times called it “A heartbreaking document of how many wrong decisions one can make in writing and performing a record”; just yesterday, Trent Reznor Twittered, “You know that feeling you get when somebody embarrasses themselves so badly YOU feel uncomfortable? Heard Chris Cornell’s record? Jesus.” Timbaland reconfigured pop music with his innovative production for Aaliyah and Missy Elliot earlier this century, but his recent hits have been far less exciting; Cornell’s Soundgarden was one of the greatest bands of the nineties, but Audioslave rocked and bored in equal measure. After indisputably great careers, are these two washed-up? And if so, who’s in worse shape?
