Background: Nicholas Edward Cave  (born 22 September 1957) is an Australian musician, singer-songwriter, author, screenwriter, composer and occasional film actor, best known as the frontman of the rock band Nick Cave and the Bad Seeds. Cave's music is generally characterised by emotional intensity, a wide variety of influences, and lyrical obsessions with death, religion, love and violence. Born and raised in rural Victoria, Cave studied art before turning to music in the 1970s. As frontman of the Boys Next Door (later renamed the Birthday Party), he became a central figure in Melbourne's burgeoning post-punk scene.
Context: Cave released his first book, King Ink, in 1988. It is a collection of lyrics and plays, including collaborations with Lydia Lunch. In 1997, he followed up with King Ink II, containing lyrics, poems, and the transcript of a radio essay he did for the BBC in July 1996, "The Flesh Made Word," discussing in biographical format his relationship with Christianity.  While he was based in West Berlin, Cave started working on what was to become his debut novel, And the Ass Saw the Angel (1989). Significant crossover is evident between the themes in the book and the lyrics Cave wrote in the late stages of the Birthday Party and the early stage of his solo career. "Swampland", from Mutiny, in particular, uses the same linguistic stylings ('mah' for 'my', for instance) and some of the same themes (the narrator being haunted by the memory of a girl called Lucy, being hunted like an animal, approaching death and execution). On 21 January 2008, a special edition of Cave's novel And the Ass Saw the Angel was released. Cave's second novel The Death of Bunny Munro was published on 8 September 2009 by Harper Collins books. Telling the story of a sex-addicted salesman, it was also released as a binaural audio-book produced by British Artists Iain Forsyth and Jane Pollard and an iPhone app. The book originally started as a screenplay Cave was going to write for John Hillcoat.  Aside from movie soundtracks, Cave also wrote the screenplays for Hillcoat's The Proposition in 2005, and Lawless (based on the novel by Matt Bondurant) in 2011.  As proof of his interest in scripture, so evident in his lyrics and his prose writing, Cave wrote the foreword to a Canongate publication of the Gospel according to Mark, published in the UK in 1998. The American edition of the same book (published by Grove Press) contains a foreword by the noted American writer Barry Hannah.  Cave is a contributor to a 2009 rock biography of the Triffids, Vagabond Holes: David McComb and the Triffids, edited by Australian academics Niall Lucy and Chris Coughran.
