Duncan never plays out unless he's got these in his bag ...

Dizzee Rascal & Groove Armada - Bonkers / Superstylin'
Bootleg I made for DJ sets which has been going down really well. 
 
MSTRKRFT feat John Legend - Heartbreaker (Laidback Luke Remix)
The original is awesome but the LL mix adds a bit of an extra punch combined with real 'hands in the air' pianos.
 
Deadmau5 feat Rob Swire - Ghosts N Stuff
This was my favorite Deadmau5 track already, but now it has a vocal courtesty of Rob Swire from Pendulum. Takes a couple of listens if you already know the original but I think this could be one of this summers late hits. 
 
Temper Traps - Sweet Disposition (Axwell & Dirty South Remix)
Really nice sounds to this, and the break-down still gives me hairs on the back of my neck. 
 
Medina - U & I (Deadmau5 Remix)
Just a great record, made even better by the mau5. Already being played by everyone from Tiesto to David Guetta, I reckon this will be really big.
