The deeper you dig into Marilyn Manson's shock rock, the more nightmarish his music becomes. With bulldozing power chords and heavy riffs, “Irresponsible Hate Anthem” shows off his metal chops, while “Mechanical Animals” is a carefully engineered interface between candied glam and electronic music. Surprisingly earthy, “Cupid Carries a Gun” is postmodern blues as elegant as a Gothic cathedral.
