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

Zoo TV: Live from Sydney is a concert video release by rock band U2 from the "Zoomerang" leg of their Zoo TV Tour.  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.  It won the Grammy Award for Best Music Video, Long Form in 1994.  The show was also broadcast around the world live on pay-per-view. <SEP>  It is the third track from their 1993 album "Zooropa" and was released in June 1993 as the album's first single.  The song features a monotonous mantra of "don't" commands spoken by guitarist the Edge amidst a backdrop of various sound effects and samples.  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.  Lead singer Bono and drummer Larry Mullen Jr. provided backing vocals on the track.  The song received remixes from Paul Oakenfold, Rollo Armstrong and Rob Dougan. "Numb" is a song by rock band U2. <SEP> Icelandic music composer and singer Björk has embarked on seven concert tours, with all of them being worldwide.  After her split up with The Sugarcubes, Björk embarked in her first concert tour to promote "Debut".  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.  The following year, she performed on the worldwide Post Tour which was extensively long and critically lauded.  The tour visited different festivals and arenas throughout Europe, North America, Oceania and Asia and featured the first performance in South America.  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.  The Tour was extended in 1998 after a cancelled North America tour with the Radiohead.  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.  The tour was critically lauded and financially expensive.  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>  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. The Zoo TV Tour (also written as ZooTV, ZOO TV or ZOOTV) was a worldwide concert tour by rock band U2.
