In a more helpful post - seeing as you like the wobbly, Transformers-having-an-epileptic-fit type festival music search for the following artists:
16 bit
Excision
Downlink
Knife Party
Doctor P
12th Planet
Antiserum ("Trap")
Trolley Snatcha
All the above artists apart from Trolley Snatcha are banned from my computer
