It's a tricky one putting on new names, even if they are sh*t hot. Not everyone dj's so they may not have heard of the guy and they might not know what to expect, skillz wise. It's gonna be down to quality promotion, timing with other techno nights in Leeds (there's some big nights leading up to NYE ) and whether the students are still kicking about.
As a promotor though, it's your call. Book the guy and see what happens, it's only money ;)
