Question: When John Frusciante returned to play guitar for the Red Hot Chili Peppers in 1998, and make the album Californication, who did he replace?
Context: Silverlake Conservatory of Music is a nonprofit educational organization formed in California.  It was founded in 2001 by Red Hot Chili Peppers bassist, Michael "Flea" Balzary and Keith "Tree" Barry (longtime touring musician with the Chili Peppers) to foster music education, with Chili Pepper's member Anthony Kiedis also on the board.  The facility organizes an annual "Hullabaloo", one of which featured performances by Red Hot Chili Peppers, Eddie Vedder and Charlie Haden, and the Chili Peppers raised $1 million for the Conservatory during an August 24, 2011 performance at Club Nokia. Californication is the seventh studio album by American rock band Red Hot Chili Peppers.  It was released on June 8, 1999, on Warner Bros.  Records and was produced by Rick Rubin.  "Californication" marked the return of John Frusciante, who had previously appeared on "Mother's Milk" and "Blood Sugar Sex Magik", to replace Dave Navarro as the band's guitarist.  Frusciante's return was credited with changing the band's sound altogether, producing a notable shift in style from the music recorded with Navarro.  The album's subject material incorporated various sexual innuendos commonly associated with the band, but also contained more varied themes than previous outings, including lust, death, contemplations of suicide, California, drugs, globalization, and travel. Exquisite Corpse is the debut EP by American alternative rock band Warpaint, self-released in late 2008 and subsequently re-released on October 6, 2009 on Manimal Vinyl.  Recorded in 2007, the EP was mixed by then-Red Hot Chili Peppers guitarist John Frusciante, and features current Red Hot Chili Peppers guitarist Josh Klinghoffer performing drums on "Billie Holiday" and guitar on "Krimson". Red Hot Chili Peppers 1984 Tour was a concert tour by Red Hot Chili Peppers to support their 1984 debut album, "The Red Hot Chili Peppers".  Following the band's brief first tour the previous year, original members, Hillel Slovak and Jack Irons left the band to tour and record with their own band, What Is This?  who had also obtained a record contract shortly before the Chili Peppers did.  Slovak and Irons considered the Chili Peppers a side project and What Is This?  to have the brighter future.  In late 1983, auditions were held and Irons was quickly replaced by Cliff Martinez, best known for his work with The Weirdos, The Dickies and Captain Beefheart.  Dix Denney, Martinez's Weirdo's bandmate was close to becoming the band's new guitarist however after a few rehearsals they felt Denney's style didn't match what the band wanted.  Through further auditions it came down to a guy named Mark Nine and Jack Sherman.  The band had no clue as to who Sherman was or how he got to the audition but knew he was the best fit because he instantly clicked musically with bassist Flea and Martinez. The discography of John Frusciante, who is best known as the former guitarist of the rock band Red Hot Chili Peppers, consists of eleven solo albums and four EPs, as well as two albums with collaborators Joe Lally and Josh Klinghoffer under the name Ataxia and one EP and one album under the alias of Trickfinger.  Frusciante left the Red Hot Chili Peppers in 1992 after he got tired of the growing success of the band.  He released his first solo album, "Niandra LaDes and Usually Just a T-Shirt", in 1994 on American Recordings.  His second record, "Smile From the Streets You Hold", was released in 1997 and later taken off the market at his request in 1999.  After returning to the Red Hot Chili Peppers in 1998, Frusciante recorded "Californication" with the band and subsequently released his third solo album, "To Record Only Water for Ten Days", in February 2001 on Warner Music Group. "Hump de Bump" is a song by the Red Hot Chili Peppers from their 2006 double album, "Stadium Arcadium".  The song is the fifth and final single released from "Stadium Arcadium" and final single the band would release with John Frusciante, who quit the band two years later.  Originally expected to be the fourth single for the US, Canada and Australia, ("Desecration Smile" was the fourth single released internationally) the Red Hot Chili Peppers decided to make the single and video a worldwide release thanks to the positive feedback on the video, which was directed by comedian and good friend Chris Rock.  The single was released in the US on April 7, 2007 while it was released May 10, 2007 in the rest of the world. Ataxia was a short-lived American experimental rock band formed in 2004 by guitarist John Frusciante (Red Hot Chili Peppers), bassist Joe Lally (Fugazi) and drummer Josh Klinghoffer (Red Hot Chili Peppers, Dot Hacker, The Bicycle Thief), who later succeeded Frusciante as the lead guitarist of the Red Hot Chili Peppers. Mother's Milk is the fourth studio album by American funk rock band Red Hot Chili Peppers, released on August 16, 1989, by EMI Records.  After the death of founding guitarist Hillel Slovak and subsequent departure of drummer Jack Irons, vocalist Anthony Kiedis and bassist Flea regrouped with the addition of guitarist John Frusciante and drummer Chad Smith.  Frusciante's influence altered the band's sound by placing more emphasis on melody than rhythm, which had dominated the band's previous material.  Returning producer Michael Beinhorn favored heavy metal guitar riffs as well as overdubbing that was perceived by Frusciante as excessive, and as a result Beinhorn and Frusciante constantly fought over the album's guitar sound. Automatic Writing is the debut studio album by American experimental rock band Ataxia, released on August 10, 2004 on Record Collection.  Ataxia consisted of then-Red Hot Chili Peppers guitarist John Frusciante, Joe Lally of Fugazi, and Josh Klinghoffer, Frusciante's subsequent successor in the Red Hot Chili Peppers. "Circle of the Noose" is a song by the American rock band Red Hot Chili Peppers that was originally recorded in March 1998 and intended for the follow-up album to 1995's "One Hot Minute".  However, the band fired guitarist Dave Navarro in April 1998 and the album sessions were cancelled with former guitarist John Frusciante returning shortly after; new music was recorded, which would ultimately make up their 1999 album, "Californication".  "Circle of the Noose" had circulated amongst rare collector’s circles for eighteen years and remained one of the most talked about unreleased songs amongst fans until a rough mix of the song was finally leaked to the internet in February 2016.  The song is a tribute to Nusrat Fateh Ali Khan and samples one of his songs.
