I had always cared for Mutiny far more than Junkyard, each song was darker, meaner and more psychopathic than the next. The whole bloodied mess ends with Deep in the Woods which has got to be one of Cave's darker moments. Throw in the Birthday Party's final EP - Mutiny and the transition to the (slightly) more refined and knowing Bad Seeds is achieved.
Both EPs are jagged and confrontational - just look at the sleeve art and you'll get the picture. Masterpieces both that demand to be loved unconditionally like incarcerated kin.
