SAN DIEGO— Puddle Of Mudd, a dreary nü-metal rock band that cites Led Zeppelin, Black Sabbath, and Metallica as influences, is obviously not listening to those influences. "Zep, Sabbath, Metallica, Maiden, Aerosmith—growing up, that's what we listened to, and that's what shaped our sound," said lead singer Wes Scantlin, whose mopey, monotone vocals in no way bear the stamp of Robert Plant, Steven Tyler, or his other idols. Scantlin, who made the comments during an interview Monday with Spin reporter Charles Aaron, failed to say which part of Puddle Of Mudd's atrocious new ballad "Drift & Die" resembles "When The Levee Breaks" or "Sweet Emotion."
