The 'again' is because I went to exactly the same festival this time last year and started the exact same thread.
Heres the lineup:

Definates:
Kraftwerk
Massive Attack
Michael Nyman
Squarepusher
Future Sound of London
Dan le sac vs. Scroobius Pip
any suggestions and I may well go check them out, though it would be nice if you wrote a sentence or two to let me know why they're worth my time.
thanks!
