Question: In what year did The Who release the double album rock opera that preceded the Who's Next studio album?
Context: Holy Water is the ninth studio album by the English hard rock band Bad Company, and their third with Brian Howe as lead vocalist.  The album was released on June 12, 1990.  It went platinum, selling over 1,000,000 units, and climbed to #35 on The Billboard Top Pop Albums Chart.  The first single "Holy Water", was a #1 Billboard Album Rock Track for two weeks during the Summer of '90 as the band toured the U.S. with Damn Yankees.  The single "If You Needed Somebody" became a major hit in early 1991, reaching # 16 on Billboards Hot 100 chart and #2 (for two weeks) on the Album Rock chart.  "Boys Cry Tough"(#3), "Stranger, Stranger"(#9) and "Walk Through Fire"(#28 Hot 100 chart / #14 Album Rock chart) also received substantial airplay. Quadrophenia is the sixth studio album by the English rock band The Who, released on 26 October 1973 by Track Records.  It is a double album and the group's second rock opera.  The story follows a young mod named Jimmy and his search for self-worth and importance, set in London and Brighton in 1965.  It is the only Who album to be entirely composed by Pete Townshend. Tommy is the fourth studio album by the English rock band The Who, a double album first released in May 1969.  The album was mostly composed by guitarist Pete Townshend as a rock opera that tells the story about a deaf, dumb and blind boy, including his experiences with life and his relationship with his family. Up the Downstair is the second studio album by British progressive rock band Porcupine Tree, first released in May 1993.  It was originally intended to be a double album set including the song "", which was instead released as a single in 1992, and other material that ended up on the "Staircase Infinities" EP (1994).  In 2005, it was partially re-recorded, fully re-mixed, remastered and re-released along with the "Staircase Infinities" EP as a double album.  The re-release contains a new mix by Steven Wilson, along with recorded drums by Gavin Harrison that replace the electronic drums of the original version.  Steven Wilson has stated that the title of the album came from a line in the song "Voyage 34."  There is still a title track, however.  Another re-release on double vinyl was pressed on 14 August 2008 on Kscope records.  This is identical to the 2005 release, except it is printed on coloured vinyl and the "Staircase Infinities" disc contains the song "Phantoms". Best: Third Universe (stylized as BEST～third universe～) is the third greatest hits album by Japanese recording artist Kumi Koda.  It was released as a double album with her eighth studio album "Universe" on February 3, 2010 by Rhythm Zone.  The greatest hits album includes singles between May 2006 "Koi no Tsubomi" and her December 2008 single "Stay with Me", with a bonus disc with newly recorded material.  As a double album, it was released in four different formats; a two album bundle, a two album and DVD bundle, a two album first pressing bundle, and a two album digital release.  A fifth format was released, but only featured the compilation. The Golden Age of Grotesque is the fifth studio album by American rock band Marilyn Manson.  It was released on May 7, 2003 by Nothing and Interscope Records, and was their first album to feature former KMFDM member Tim Sköld, who joined after longtime bassist Twiggy Ramirez amicably left the group over creative differences.  It was also their final studio album to feature keyboardist Madonna Wayne Gacy and guitarist John 5, who would both acrimoniously quit before the release of the band's next studio album. The discography of Weezer, an American rock band, consists of 10 studio albums, two compilation albums, one video album, six extended plays, twenty-eight singles and twenty-four music videos. Weezer's self-titled debut studio album, often referred to as "The Blue Album", was released in May 1994 through DGC Records.  The album was a huge commercial success, peaking at number 16 on the US "Billboard" 200 and spawning the singles "Undone – The Sweater Song" and "Buddy Holly", both of which were responsible for launching Weezer into mainstream success with the aid of music videos directed by Spike Jonze.  It has sold 3.3 million copies in the United States and has been certified triple platinum by the Recording Industry Association of America (RIAA), becoming the band's best selling album to date.  Following the success of their debut album, Weezer took a break from touring for the Christmas holidays.  Lead singer Rivers Cuomo began piecing together demo material for Weezer's second studio album.  Cuomo's original concept for the album was a space-themed rock opera, "Songs from the Black Hole".  Ultimately, the "Songs from the Black Hole" album concept was dropped; the band, however, continued to utilize songs from these sessions into work for their second studio album. " Pinkerton" was released as the band's second studio album in September 1996.  Peaking at number 19 on the "Billboard" 200, it was considered a critical and commercial failure at the time of its release, selling far less than its triple platinum predecessor.  However, in the years following its release, it has seen much critical and commercial championing. Southern Rock Opera is the third studio album by the alt country band Drive-By Truckers, released in 2001.  A double album covering an ambitious range of subject matter from the politics of race to 1970s stadium rock, "Southern Rock Opera" either imagines, or filters, every topic through the context of legendary Southern band, Lynyrd Skynyrd.  The record was originally self-released on Soul Dump Records.  The album was re-released on July 16, 2002 by Lost Highway Records.  The album was financed by issuing promissory notes in exchange for loans from fans, family and friends of the band. Tommy Victor (born September 19, 1966) is the lead singer and guitarist for the heavy metal band Prong that he founded in New York City in 1986.  In the late 1980s Victor worked as a sound engineer at the trendy venue, CBGB in New York City.  After the release of "Rude Awakening" in 1996, Prong disbanded and Victor moved to Los Angeles but continued to release new Prong records.  He took a break from Prong during which Victor worked alongside rock musicians including Rob Zombie, Marilyn Manson, Trent Reznor and Glenn Danzig.  Since 2012's "Carved Into Stone", Prong have been very active again, releasing albums and touring relentlessly.  2013 saw the band release their "Official Bootleg -- Unleashed In The West"-album which featured re-recordings of 17 classic Prong tracks.  The next studio album "Ruining Lives" was released in 2014 and 2015 sees the band release their first ever covers album entitled "Songs From The Black Hole".  Victor is also currently working with Glenn Danzig on his upcoming Danzig album.  He is also part of the hard rock, heavy metal, hardcore punk and punk rock supergroup Teenage Time Killers. Who's Next is the fifth studio album by English rock band The Who.  It developed from the aborted "Lifehouse" project, a multi-media rock opera written by the group's Pete Townshend as a follow-up to the band's 1969 album "Tommy".  The project was cancelled due to its complexity and conflicts with Kit Lambert, the band's manager, but Townshend was persuaded to record the songs as a straightforward studio album.
