The band sought to record their next album Blood Sugar Sex Magik in an unconventional setting, believing it would enhance their creative output. The band's producer Rick Rubin suggested the mansion magician Harry Houdini once lived in, to which they agreed. A crew was hired to set up a recording studio and other equipment required for production in the house. The band decided that they would remain inside the mansion for the duration of recording, though Smith, convinced the location was haunted, refused to stay.  During this stage, Kiedis began to write about anguish, and the self-mutilating thoughts he would experience as a result of his heroin and cocaine addiction.   Chili Peppers producer Rick Rubin stumbled upon one of Kiedis's poems that would become the lyrics to " Under the Bridge ", and suggested Kiedis show it to the rest of the band. Kiedis was apprehensive because he believed the lyrics to be "too soft" and unlike the band's style. After singing the verse to Frusciante, they began structuring the song the next day.  The two worked for several hours arranging chords and melodies until they both agreed it was complete.  The song later became a major hit, peaking at number two on the Billboard 100. When Blood Sugar Sex Magik was released on September 24, 1991, it received an overwhelmingly positive critical response. The album peaked at number three on the Billboard Hot 200, and went on to sell over seven million copies in the . alone. The album's ensuing tour was critically acclaimed—the Chili Peppers commonly performed shows with over twenty thousand in attendance.  Seattle -based grunge band Nirvana also toured with them during the West Coast leg of their United States tour.  The massive attention the Chili Peppers started receiving caused Frusciante to feel extremely uncomfortable, and he abruptly quit the band during the Japanese leg of the album's tour. The band hired guitarist Arik Marshall to complete the remaining tour dates. The band appeared live on the Grammy's ceremony with George Clinton's P-Funk collective and many others, performing a medley that included " Give It Away ".
