Ableton/Serato blah blah, its still on the whole mixing other peoples tunes and samples together. Watching a dj using only a Laptop and no turntables is an awful experience in my opinion, extremely dull, and no way of knowing how much of it is just pre programmed at home before the gig.
The Djs youve listed though are utter trance garbage though. And Id never compare a bloke playing somebody elses records and cds as a proper gig, thats blatently ridiculous imo.
Prince at the O2 was possibly the best performance by an artist I have ever seen, also very good gigs of the year were:
LCD Soundsystem at Astoria
Underworld @ Camden Roundhouse
The Aliens at Glastonbury
Beastie Boys at Brixton Academy
