OK Just a heads up, not that I believe it because Last FM is notoriously a shit source, but they have the following listed as lineup for Friday the 24th. Atlas Genius, Deadmau5, DIIV, Disclosure, Empire of the Sun, Imagine Dragons, Knife Party, The XX and Youth Lagoon. I am thinking this info was stolen from this forum?
I've been adding all of those. It's all based on speculation on the board.
