This is without a doubt my favourite set from the two though I believe the beginning may be Sean Cusick & Jimmy Van M warming up, following by Sasha & Digweed on the warmup.
Either way, this set has always been with my since I downloaded it fresh from DJ Mixes 2k back in the day but I’d never seen the video that goes with it. Stumbled across it just now by accident 🙂
This set is sometimes mislabeled as Sasha & Digweed – Live at Fabric which they played a couple of weeks earlier.
