I'd agree with the majority (if not all) of the views here. I have to say though that when I've seen the liberators play out 2 hours of London Acid is way way too much for me. I can't handle it, it doesn't change or progress enough for me, it's pretty much the same formula as Jimmah said.
Don't get me wrong I do like London Acid stuff at particular times but not all night long I suppose. I have bought a few Cluster, Smitten etc but obviously these aren't the only type of Techno that I buy.
As T said throwing a few London Acid trax into a set can work quite well but not for a whole set...
