If you’re into an eclectic mix of drums, guitar, politics and piano then spending nearly twenty bucks on Muse’s new album “Black Holes and Revelations,” is worth every cent. Their sixth and possibly most bitter album yet is finally completed with lyrics such as “Corrupt, you’re corrupt” and “You’ll burn in hell,” but you’d never notice it by all the appealing and melodic art taking your attention away from the resentful libretto.
