■ Slipknotõs second studio album is the sound of chaos. Recorded and produced at Dave Grohl-endorsed rustic recording refuge Sound City, from start to fi nish, Iowa is a record infused with pain. At the time of recording, many of the band were riddled with drug addictions. Corey Taylor Ð himself battling alcoholism Ð is said to have recorded the title-track completely naked, vomiting and cutting himself with broken glass. Not only that, but producer Ross Robinson came off his dirt bike and fractured his back during recording. He returned to the fray after a mere day in hospital, Òputting all his pain into the albumó.
