Paul Heslin was raised in the capital city of Australia in a dark well of hyper-christian homeschooling, before peeling the layers off and beginning to grapple with the world of electronic sound. In 2008, after completing a university degree in digital sound and composition, he vanished overseas to England and France for an extensive period of musical development, returning to Australia in late 2010 with a spiky melange of facial hair and the transformative rubbernecker ep.

Swans is an influential band from New York City, New York, United States, active from 1982 to 1997, reformed in 2010, led by singer, songwriter and multi-instrumentalist Michael Gira. Marginally associated with the no wave scene at first, their original sound was slow and heavy, with live performances that were often so brutal and physical that in a number of instances certain audience members were made ill, police were called and venues were shut down. This early physical sound is possibly best heard on the live album Public Castration Is a Good Idea.
