The Chemical Brothers - (Opening DJ set sample) @ Future Music Festival 2012

The Chemical Brothers DJ set always performs in the dark, minimal lighting and cannot have any light shine on the 2 brothers. We saw this set in Singapore last year. Thought that something went wrong but it’s obvious now that this is what they want. Just the sound is good enough and it was! Please correct me if I’m wrong about this. Have anyone heard the first song before? I’ve never heard of it.
