Here is a link to download LA Riots Live at ILOVETECHNO 2008 in Belgium, Ghent. Lineup included Justice, Underworld, Boys Noize, Digitalism, Booka Shade, Hot Chip, Mehdi, Feadz, Busy P, Crookers, Tocadisco, Audion, Ritchie Hawtin etc. etc. Not sure how they recorded this but you can hear the crowd chanting (like at a soccer game) all throughout. Parts of it drops out for seconds at a time but you get nearly an hour of the set.
