Jerome Hill @ the building next to the sea of fridges on Carpenters Road last year.
Adam Beyer at|Atomic Jam about 5 years ago. Like having someone hammer nails into your skull for two hours.
Dave Clarke at Pontins in Southport after I'd given up on him for being a dull twat and then he pulled out 2 hours of outrageous non stop (but danceable) turntablism.
James Ruskin most times I've seen him.
Ben Sims @ Lost Weekend Nottingham
D.A.V.E - too many great sets to pick one.
Derrick Carter every time
