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 was born on 22 September 1957 in Warracknabeal, a small country town in the state of Victoria, Australia, to Dawn Cave (nee Treadwell) and Colin Frank Cave. As a child, he lived in Warracknabeal and then Wangaratta in rural Victoria. His father taught English and mathematics at the local technical school; his mother was a librarian at the high school that Nick attended. Cave's father introduced him to literary classics from an early age, such as Crime and Punishment and Lolita, and also organised the first symposium on the Australian bushranger and outlaw Ned Kelly, with whom Nick was enamoured as a child.  When Cave was 9 he joined the choir of Wangaratta's Holy Trinity Cathedral. At 13 he was expelled from Wangaratta High School. In 1970, having moved with his family to the Melbourne suburb of Murrumbeena, he became a boarder and later day student at Caulfield Grammar School. He was 19 when his father was killed in a car accident; his mother told him of his father's death while she was bailing him out of a St Kilda police station where he was being held on a charge of burglary. He would later recall that his father "died at a point in my life when I was most confused" and that "the loss of my father created in my life a vacuum, a space in which my words began to float and collect and find their purpose".  After his secondary schooling, Cave studied painting at the Caulfield Institute of Technology in 1976, but dropped out the following year to pursue music. He also began using heroin around the time that he left art school.  Cave attended his first music concert at Melbourne's Festival Hall. The bill consisted of Manfred Mann, Deep Purple and Free. Cave recalled: "I remember sitting there and feeling physically the sound going through me."
