Eighth studio album by the acclaimed English singer-songwriter. 'Aerial' is Bush's first double album and was released after a twelve-year absence from the music industry. The album is divided into two thematically distinct collections. The first disc, subtitled 'A Sea of Honey', features a set of unrelated songs including the hit single 'King of the Mountain', a Renaissance-style ode to her son 'Bertie', performed with period instruments, and 'Joanni', based on the story of Joan of Arc. The second disc, subtitled 'A Sky of Honey', consists of a single piece of music revelling in the experience of outdoor adventures on a single summer day, beginning in the morning and ending twenty-four hours later with the next sunrise.
