I do not feel required to believe that Skrillex is a human being. My top three theories to explain the existence of such a thing are as follows…
1: Skrillex is the name of a program designed by a post-grad computer engineering student to simulate industrial workplace noise. After a night of heavy drinking said student inadvertently messed up some of the audio filters and induced a series of overlapping sound loops, then realised that the resulting cacophony might go down well at next weekend’s beer and ecstasy mixer.
2: Skrillex is an ancient fax-modem, forgotten about in a storage cupboard but still connected to the net, which has achieved sentience and a recording contract.
3: Skrillex is a member of an unknown, sapient, deep-sea dwelling species that is attempting to communicate with us by modulating its vocalisations for propagation through air rather than water. It’s not very good at it.
