According to Tool drummer Danny Carey in Revolver Magazine Presents Tool
, "A lot of the songs for Undertow
were already written when we did Opiate
, but we felt like no one would take us seriously unless we recorded only our most aggressive, in-your-face song and put them out there at one time. And I think that got us typecast as a metal band. It's kind of funny, because the song I thought was the least aggressive, 'Opiate,' was the more popular on the record."
