As 1989 rolled around the band was back to the two founding members, singer Anthony Kiedis and bassist Flea. After firing a few band members, an eighteen year old guitarist by the name of John Frusciante auditioned for the band. Frusciante had been an avid fan of the Chili Peppers for a long time and looked to take the chance. His audition was flawless as he and Flea jammed for a long while. This find will prove to be one of the greatest things that could happen to the band. They then auditioned a friend of a dedicated fan by the name of Chad Smith. His audition went great as he not only kept up with Flea’s beats but also began to lead him. With this new band, they record their fourth studio album, Mother’s Milk. In August 1989 the album was released and topped the charts at number 52. In 1990 the band switched labels from EMI to Warner Bros. Records. To record their new album, the new producer Rick Rubin decided it would be best to have the band live in seclusion during the whole recording time. At this time the band lived in a mansion for sixth months recording their new album Blood Sugar Sex Magik. The album was released in September 1991. The album was an international sensation where songs such as Give It Away and under the bridge were number 1 and number 2 on the charts. Also, the album is listed as number 310 on the Rolling Stones list of 500 greatest albums of all time.  The bands success and drug addictions took their toll on Frusciante and he quit the band in the middle of the Japan tour. After using a few replacement guitarists for the tour, they eventually hired Jane’s Addiction Guitarist Dave Navarro.
