Question: The Zoo TV Tour, by rock band U2, was staged in support of their 1991 album "Achtung Baby", was produced by what two people?
Context: The Zoo TV Tour (also written as ZooTV, ZOO TV or ZOOTV) was a worldwide concert tour by rock band U2.  Staged in support of their 1991 album "Achtung Baby", the tour visited arenas and stadiums from 1992 to 1993.  To mirror the new musical direction that the group took with "Achtung Baby", the tour was intended to deviate from their past and confound expectations of the band.  In contrast to U2's austere stage setups from previous tours, the Zoo TV Tour was an elaborately staged multimedia event.  It satirised television and media oversaturation by attempting to instill "sensory overload" in its audience.  To escape their reputation for being earnest and overly serious, U2 embraced a more lighthearted and self-deprecating image on tour.  Zoo TV and "Achtung Baby" were central to the group's 1990s reinvention. Achtung Baby ( ) is the seventh studio album by Irish rock band U2.  It was produced by Daniel Lanois and Brian Eno, and was released on 18 November 1991 on Island Records.  Stung by criticism of their 1988 release, "Rattle and Hum", U2 shifted their musical direction to incorporate influences from alternative rock, industrial music, and electronic dance music into their sound.  Thematically, "Achtung Baby" is darker, more introspective, and at times more flippant than their previous work.  The album and the subsequent multimedia-intensive Zoo TV Tour were central to the group's 1990s reinvention, by which they abandoned their earnest public image for a more lighthearted and self-deprecating one. Zoo TV Live is a live album by the Irish rock band U2.  It was released exclusively to subscribing members of U2's official site, replacing "U2.COMmunication" on 20 November 2006.  This double CD features the same material that is on the "" VHS and DVD releases, as well as one bonus track from the Zoo TV special, "Tryin' to Throw Your Arms Around the World."  Although U2's website refers to the album as ZOO2Live, the album is titled "Zoo TV Live" according to the actual CDs.  This album was discontinued from the website for the release of "" in 2007.  Recently for the U2.com 2012/13 subscriber offer, the album was included as part of a 'bundle' edition along with U22 and 11 instant downloads from U22. The PopMart Tour was a worldwide concert tour by rock band U2.  Launched in support of the group's 1997 album, "Pop", the tour's concerts were performed in stadia and parks in 1997 and 1998.  Much like the band's previous Zoo TV Tour, PopMart was elaborately staged.  Its lavish stage design had a 165 ft wide LED screen, a 100 ft -high golden arch, and a large mirror-ball lemon.  As with the Zoo TV tour, the band delivered an image and performance that were ironic and self-mocking, deviating from its earnest performances of the 1980s; the band performed in costumes that, along with the PopMart stage design, poked fun at the themes of consumerism and pop culture. From the Sky Down is a 2011 American documentary film directed by Davis Guggenheim about rock band U2 and the production of their 1991 album "Achtung Baby".  The film documents the album's difficult recording period, the band members' relationships, and the group's creative process.  Guggenheim, who was commissioned by U2 to create the film to commemorate the record's 20th anniversary, spent several months in 2011 developing the documentary.  The band were filmed during a return visit to Hansa Studios in Berlin where parts of the album were recorded, and during rehearsals in Winnipeg for the Glastonbury Festival 2011.  The film contains unreleased scenes from the group's 1988 motion picture "Rattle and Hum", along with archival footage and stills from the "Achtung Baby" recording sessions.  Development of the album's emblematic song "One" is recounted through the replaying of old recording tapes. "Zoo Station" is a song by Irish rock band U2.  It is the opening track from their 1991 album "Achtung Baby", a record on which the group reinvented themselves musically by incorporating influences from alternative rock, industrial, and electronic dance music.  As the album's opening track, "Zoo Station" introduces the band's new sound, delivering industrial-influenced percussion and several layers of distorted guitars and vocals.  Similarly, the lyrics suggest the group's new intents and anticipations.  The introduction, featuring an "explosion" of percussion and a descending glissando for a guitar hook, was meant to make the listener think the album was mistakenly not U2's latest record or that their music player was broken. "Acrobat" is a song by rock band U2.  It is the eleventh track on their 1991 album "Achtung Baby".  The critical failure of "Rattle and Hum" (1988) led the band to seek a harder sound in their music.  The song developed from a riff created by guitarist The Edge, and is played in a ⁄ time signature.  Thematically the song contains elements of hypocrisy, alienation, and moral confusion.  "Acrobat" has never been performed live, although it was rehearsed prior to the third leg of the Zoo TV Tour. AHK-toong BAY-bi Covered, stylized as (Ăhk-to͝ong Ba͞y-bi) Covered or (Ăℎk-to͝ong Ba͞y-bi) Covered, is a tribute album featuring cover versions of the 12 songs from U2's 1991 record "Achtung Baby".  It was released on 26 October 2011 as a pack-in CD with the December 2011 issue of "Q" (issue #305).  The magazine commissioned the album to commemorate the 20th anniversary of "Achtung Baby"' s original release and "Q"' s 25th anniversary.  The magazine's editor-in-chief Paul Rees said, "This is an entirely appropriate way to mark "Q"' s anniversary and that of "Achtung Baby", one of the pivotal albums in our lifetime."  The performing artists are a mix of U2's contemporaries and successors, including Jack White, Patti Smith, Nine Inch Nails, Depeche Mode, The Killers, and Garbage.  Although a tribute album, "AHK-toong BAY-bi Covered" contains a remix of "Even Better Than the Real Thing" that is credited as performed by U2. "Love Is Blindness" is a song by rock band U2, and the twelfth and final track on their 1991 album "Achtung Baby".  The song was written on piano by lead singer Bono during the recording sessions for U2's 1988 album "Rattle and Hum".  Originally intending to give the song to singer Nina Simone, the band decided to keep it for "Achtung Baby" after playing it together.  Thematically, the song describes a failing romance, mixing personal themes with imagery of metaphorical acts of terrorism.  During the recording sessions for "Achtung Baby", guitarist the Edge separated from his wife, Aislinn O'Sullivan.  The separation had a major effect on the development of the song; Bono said that the ending guitar solo was a cathartic experience for the Edge, as he snapped several guitar strings during the recording. Zooropa is the eighth studio album by Irish rock band U2.  Produced by Flood, Brian Eno, and The Edge, it was released on 5 July 1993 on Island Records.  Inspired by the band's experiences on the Zoo TV Tour, "Zooropa" expanded on many of the tour's themes of technology and media oversaturation.  The record was a continuation of the group's experimentation with alternative rock, electronic dance music, and electronic sound effects that began with their previous album, "Achtung Baby", in 1991.
