Question: Where has the artwork referenced by the title of the novel "The Garden of Unearthly Delights" housed? 
Context: The Garden Of Unearthly Delights is a novel by British author Robert Rankin.  Its title is a reference to the painting "The Garden of Earthly Delights" by the painter Hieronymus Bosch. Clam Dip & Other Delights is the 1989 grab-bag EP from Minneapolis rockers Soul Asylum.  The title and cover art are both parodies of Herb Alpert and the Tijuana Brass's album "Whipped Cream and Other Delights".  It was a humorous nod to their new record label, A&M (the "A" standing for "Alpert").  Bassist Karl Mueller sat in for the original album's model, Dolores Erickson.  Dave Ayers, the band's first manager, said that Mueller had to sit for hours in a foul-smelling combination of sour cream, paint, whipped cream and seafood.  Also, the album makes fun of the A&M logo being under the title of the album, incorporating the Twin/Tone Records logo instead. Miranda Sex Garden were a music group from London, England.  Formed in 1990, they were originally a trio of madrigal singers.  Their first album, "Madra" (1991), was entirely a cappella, with the songs all based on traditional English verse.  It took only two days to record.  By their second release, "Iris" (1992), the sound evolved into a blend of their madrigal-styled vocals with sounds reminiscent of gothic rock, dark wave, ethereal wave, and industrial music.  Their sound became increasingly dark and sophisticated over the years.  Around the time of their third album, "Fairytales of Slavery", they said they wanted to create music that evoked a "seductive garden of earthly delights, full of colour and chaos."

Earthly Delights is a record label founded in 1986 by Nigel Ayers of Nocturnal Emissions.  The label's name refers to Hieronymous Bosch's painting The Garden of Earthly Delights. The Garden of Earthly Delights is the modern title given to a triptych painted by the Early Netherlandish master Hieronymus Bosch, housed in the Museo del Prado in Madrid since 1939.  It dates from between 1490 and 1510, when Bosch was between 40 and 60 years old. The Garden of Unearthly Delights is the eighth full-length album by the British doom metal band Cathedral.  It was released on January 26, 2006.  The album title is inspired by the Hieronymous Bosch painting "The Garden of Earthly Delights."  The album was recorded at New Rising Studios and produced by Warren Riker. A cherub ( ; also pl.  cherubim; Hebrew: כְּרוּב‎ ‎ "kərūv", pl.  , "kərūvîm"; Latin "cherub", pl.  "cherubin, cherubim"; Syriac ܟܪܘܒܐ) is one of the unearthly beings who directly attend to God according to Abrahamic religions.  The numerous depictions of cherubim assign to them many different roles; their original duty having been the protection of the Garden of Eden.  Angelic status is not attributed to cherubim in the Old Testament (at least not explicitly); only in later sources such as "De Coelesti Hierarchia" are they identified as a hierarchical rank of angels. Martha Clarke (born June 3, 1944) is an American theater director and choreographer noted for her multidisciplinary approach to theatre, dance, and opera productions.  She is the creator of plotless, dreamlike works that are perhaps described by the term "moving paintings.  Her work frequently emphasizes striking visual tableaux, often directly inspired by visual art, especially painting.  Though dance is the primary basis of Clarke's training, she has maintained a career which spans and melds dance, theater, the visual arts, and opera.  Probably her best-known original work is "The Garden of Earthly Delights" (1984), an exploration in theatre, dance, music and flying of the famous painting of the same name by Hieronymus Bosch.  In June 2007, a new version of the show opened the 30th anniversary of the American Dance Festival.
