Question: How many Deftones albums were released before their album released in 2000?
Context: Sexy Sweet Thing is a 2000 album released by the funk/R&B group Cameo.  This 13-track release was Cameo's first full album of new material since "In the Face of Funk" in 1994, and peaked at #64 on the Top R&B/Hip-Hop Albums charts.  To date, this has been the last album released by Cameo; the only releases since "Sexy Sweet Thing" have been re-releases and compilation albums. Soulfly is an American heavy metal band formed in 1997 and based in Phoenix, Arizona.  The original lyrical content revolved around spirituality, political and religious themes, with later albums encompassing other themes including war, violence, aggression, slavery, hatred and anger.  Soulfly is led by former Sepultura frontman Max Cavalera, who formed the band after he left the Brazilian group in 1996.  To date the band has released ten studio albums, one tour EP, twenty-three singles, one video album, and twelve music videos.  Their debut album, "Soulfly", was released on April 21, 1998, while their newest album, "Archangel", was released on August 14, 2015.  In a interview with Max in 2015, the name Soulfly is taken from the song "Headup" of Deftones. Bon Appetit is the third full-length album released by D.I.T.C. rapper O.C.; released in 2001.  As on previous efforts, Buckwild handles the bulk of the production; he was responsible for 12 out of 15 songs on the album.  The other contributions come from Lord Finesse (who also produced on both of the two previous albums) and "Ahmed" who OC previously worked together with on the self-titled D.I.T.C. album released in 2000.  Guest appearances are as usual kept to a minimum on Bon Appetit and in the family as A.G., "The Ghetto Dwellas" and "A Bless" appears on one track each.  Two rappers by the name of UNI and TL, who still remains unknown to this day, trades verses with O on the title track and rapper Jay-Z perform the hook on the hidden bonus track "Bonafide" (originally released in 1999 on a limited 12" single). Sergio Vega (born August 25, 1970) is an American musician of Puerto Rican descent.  He is the bassist of post-hardcore band Quicksand, which originated in New York City in 1990.  In 1995, Quicksand disbanded, although they reunited again in 1997 to tour with Deftones.  After this tour, the band desired to write a follow-up to their last album "Manic Compression", although tensions between bandmates caused the band to split up again, until June 2012 when another reunion was announced.  Vega began playing for Deftones, replacing Chi Cheng after Cheng was involved in a car accident which caused him to enter a semi-conscious state in November 2008 and led to his eventual death on April 13, 2013.  With Deftones he released the albums "Diamond Eyes" (2010) and "Koi No Yokan" (2012), and worked on the band's eighth studio album, "Gore", which was released on April 8, 2016. "Back to School (Mini Maggit)" is a song composed by the American alternative metal band Deftones.  It is an altered version of the song "Pink Maggit" from the band's 2000 album "White Pony".  Shortly after the album's initial release, in a contentious move by the band's label, Maverick Records, it was re-released with "Back to School (Mini Maggit)" added on.  The song's style has been described as nu metal as well as rap rock. "Be Quiet and Drive (Far Away)" is the second single released from the American alternative metal band Deftones' second album, "Around the Fur".  It was their first single to chart on the US charts, peaking at number 29 on the Mainstream Rock Tracks chart, and within the top 50 in the UK Singles Chart.  Although it was a more modest hit than the follow-up, "Change (In the House of Flies)", it was included in the game "Dave Mirra Freestyle BMX", released in 2000.  An acoustic version appeared on the soundtrack to the film "Little Nicky".  This version, which featured Adam Sandler, the star of the movie, as well as Jonah Matranga of Far, was also included on the Deftones' "B-Sides & Rarities" album. Blue-Sky Research is Taproot's third major label album which was released on August 15, 2005 internationally and a day later in the United States.  Smashing Pumpkins frontman Billy Corgan co-wrote three songs on the album.  Deftones guitarist Stephen Carpenter and Jonah Matranga from Far and Onelinedrawing make guest appearances.  The band wrote over 80 songs for the effort. " Calling" was released as the first single and was a moderate hit, while the second single, "Birthday", followed quietly.  It is Taproot's last album with Atlantic Records, as both parties have decided to part ways.  It has a different, softer, more alternative melody from the first two albums.  The album has sold over 140,000 copies in the U.S., despite little label support. Idol is Dead (stylized IDOL is DEAD) is the second studio album released by Japanese idol group BiS on October 28, 2012.  It is their first original album released on a major label, as well as the first (and only) full album released with the "Quintet" lineup (Pour Lui, Nozomi Hirano, Yufu Terashima, Rio Michibayashi, and Yurika Wakisaka).  The album continues the style of BiS's previous releases, containing songs of different types of rock.  It also continues the tradition of their studio albums containing a cover, in this case Shinichi Osawa's "Our Song", arranged in a Shoegaze style.  The four tracks ("nerve", "My Ixxx", "primal."  and "IDOL") from their independent label days have been re-recorded. White Pony is the third studio album by American alternative metal band Deftones, released on June 20, 2000 by Maverick Records.  It marked a significant growth in the band's sound and is considered a turning point for the band in terms of experimentation, employing an increasingly experimental rock sound and incorporating more new wave, dream pop, trip hop, shoegaze and post-rock influences into the alternative metal sound for which the group had become known.  Upon release and retrospectively, the album was met with overall critical acclaim and is generally regarded by fans and critics alike as one of their most mature outings.  "White Pony" is also their highest-selling album to date.  The album was certified platinum by the RIAA on July 17, 2002.  The album includes three successful singles ("Change (In the House of Flies)", "Back to School (Mini Maggit)" and "Digital Bath") as well as the 2001 Grammy Award-winning track for Best Metal Performance, "Elite". The full discography of rock musician Myles Kennedy consists of eleven studio albums, two concert films, four live albums, two extended plays, and thirteen singles in total, in addition to eleven studio tracks that he has appeared on as a featured artist, one of which was a single.  Born in Boston on November 27, 1969, Kennedy is currently a member of the rock band Alter Bridge, with whom he has released four studio albums, two concert films, and several singles.  He is also the frontman of Slash's touring group, and with Slash he has released a live album, "Live in Manchester", the first of a series of live albums released throughout the summer of 2010, and "", another live album released in 2011.  In 2012, he released a collaboration studio album with Slash titled "Apocalyptic Love", which is billed to Slash featuring Myles Kennedy and the Conspirators, as well as the 2014 followup titled "World on Fire".  With The Mayfield Four, he released two studio albums, two extended plays, and four singles; with Citizen Swing, two studio albums; and with Cosmic Dust, one studio album.
