Album/film Review: Nick Cave - Skeleton Tree/Once More Time With Feeling

Nick Cave was deep into recording his sixteenth studio album when, on July 14, 2015, his 15-year-old son Arthur fell to his death from a cliff near the family home in Brighton.
The extent to which the tragedy has shaped new album Skeleton Tree is unclear: is it truly possible to channel parental grief into something so trivial as a rock song? Should one even try? Or is the braver response to stoically carry on before — for the singer to honour his child by making just another Nick Cave record?
