Question: What is the name of the band that sang Numb during their 1992 to 1993 Zoo TV concert tour?

<P0-S0> Zoo TV: Live from Sydney is a concert video release by rock band U2 from the "Zoomerang" leg of their Zoo TV Tour. <P0-S1>  Recorded on Saturday, 27 November 1993 at Sydney Football Stadium on the band's featured stop in Sydney, Australia, it was released in May 1994 on VHS and Laserdisc, and re-released in September 2006 on DVD. <P0-S2>  It won the Grammy Award for Best Music Video, Long Form in 1994. <P0-S3>  The show was also broadcast around the world live on pay-per-view. <SEP> <P1-S0>  It is the third track from their 1993 album "Zooropa" and was released in June 1993 as the album's first single. <P1-S1>  The song features a monotonous mantra of "don't" commands spoken by guitarist the Edge amidst a backdrop of various sound effects and samples. <P1-S2>  The noisy composition and lyrical concept for "Numb" were inspired by the theme of sensory overload, which had prominently been incorporated into the Zoo TV Tour. <P1-S3>  Lead singer Bono and drummer Larry Mullen Jr. provided backing vocals on the track. <P1-S4> "Numb" is a song by rock band U2. <P1-S5>  The song received remixes from Paul Oakenfold, Rollo Armstrong and Rob Dougan. <SEP> <P2-S0> Icelandic music composer and singer Björk has embarked on seven concert tours, with all of them being worldwide. <P2-S1>  After her split up with The Sugarcubes, Björk embarked in her first concert tour to promote "Debut". <P2-S2>  The Tour lasted one year, from August 1993 to July 1994, and included a concert to support the U2 on their Zoo TV Tour at the Wembley Stadium. <P2-S3>  The following year, she performed on the worldwide Post Tour which was extensively long and critically lauded. <P2-S4>  The tour visited different festivals and arenas throughout Europe, North America, Oceania and Asia and featured the first performance in South America. <P2-S5>  In November 1997, with the release of "Homogenic" she embarked on the Homogenic Tour after promoting the album with a short promotional tour earlier during the same year. <P2-S6>  The Tour was extended in 1998 after a cancelled North America tour with the Radiohead. <P2-S7>  After the end of the tour in 1999, Björk embarked on the Vespertine World Tour which featured performances with a full Orchestra in Opera houses. <P2-S8>  The tour was critically lauded and financially expensive. <P2-S9>  In 2003 she toured throughout Europe and North America (including one stop in Asia) for her Greatest Hits Tour, performing in Stadiums and headlining major European Festivals. <SEP> <P3-S0>  Staged in support of their 1991 album "Achtung Baby", the tour visited arenas and stadiums from 1992 to 1993. <P3-S1>  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. <P3-S2>  In contrast to U2's austere stage setups from previous tours, the Zoo TV Tour was an elaborately staged multimedia event. <P3-S3>  It satirised television and media oversaturation by attempting to instill "sensory overload" in its audience. <P3-S4> The Zoo TV Tour (also written as ZooTV, ZOO TV or ZOOTV) was a worldwide concert tour by rock band U2. <P3-S5>  To escape their reputation for being earnest and overly serious, U2 embraced a more lighthearted and self-deprecating image on tour. <P3-S6>  Zoo TV and "Achtung Baby" were central to the group's 1990s reinvention.
