Question: What happened first, the release of Zooropa or Zoo TV Tour?

<P0-S0> "Numb" is a song by rock band U2. <P0-S1>  It is the third track from their 1993 album "Zooropa" and was released in June 1993 as the album's first single. <P0-S2>  The song features a monotonous mantra of "don't" commands spoken by guitarist the Edge amidst a backdrop of various sound effects and samples. <P0-S3>  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. <P0-S4>  Lead singer Bono and drummer Larry Mullen Jr. provided backing vocals on the track. <P0-S5>  The song received remixes from Paul Oakenfold, Rollo Armstrong and Rob Dougan. <SEP> <P1-S0> The MYH16 gene encodes a protein called myosin heavy chain 16 which is a muscle protein in mammals. <P1-S1>  At least in primates, it is a specialized muscle protein found only in the temporalis and masseter muscles of the jaw. <P1-S2>  Myosin heavy chain proteins are important in muscle contraction, and if they are missing, the muscles will be smaller. <P1-S3>  In non-human primates, MYH16 is functional and the animals have powerful jaw muscles. <P1-S4>  In humans, the MYH16 gene has a mutation which causes the protein not to function. <P1-S5>  Although the exact importance of this change in accounting for differences between humans and other apes is not yet clear, such a change may be related to increased brain size and finer control of the jaw which facilitates speech. <P1-S6>  It is not clear how the MYH16 mutation relates to other changes to the jaw and skull in early human evolution (for example, whether the MYH16 mutation happened first and led to other changes, or whether the MYH16 mutation happened after other changes made the MYH16 protein no longer necessary). <SEP> <P2-S0>  Staged in support of their 1991 album "Achtung Baby", the tour visited arenas and stadiums from 1992 to 1993. <P2-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. <P2-S2>  In contrast to U2's austere stage setups from previous tours, the Zoo TV Tour was an elaborately staged multimedia event. <P2-S3> The Zoo TV Tour (also written as ZooTV, ZOO TV or ZOOTV) was a worldwide concert tour by rock band U2. <P2-S4>  It satirised television and media oversaturation by attempting to instill "sensory overload" in its audience. <P2-S5>  To escape their reputation for being earnest and overly serious, U2 embraced a more lighthearted and self-deprecating image on tour. <P2-S6>  Zoo TV and "Achtung Baby" were central to the group's 1990s reinvention. <SEP> <P3-S0>  Produced by Flood, Brian Eno, and The Edge, it was released on 5 July 1993 on Island Records. <P3-S1> Zooropa is the eighth studio album by Irish rock band U2. <P3-S2>  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. <P3-S3>  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.
