So, this could go two ways: it’s either the single worst fake DJ performance of all time (there’s pretending to mix, and then there’s ghost-riding the EQs like this), or it’s the DJ’s mate messing about rather than a back-to-back – he does have a press wristband rather than an artist’s one, though that’s hardly conclusive of anything. But either way, it’s pretty funny. Wonder what Guetta thinks.
