Describe in a tweet: Forgive the cliche, but "it's on".

What went down: This is astonishing. It's barely half-eight, but three thousand people are getting on like it's 2am in a sold out club in somewhere (supposedly) cooler, like Berlin. The first thirty or forty rows of people have their hands in the air like they do indeed not care.

The highlight: Quite a few. Alexander Ridha clambering about the decks is one. That bleepy remix of 'Beat it' was definitely another. His own 'Jeffer' and a few other newbies going down well. The criminally overlooked Felix Da Housecat tune 'Elvi$' wrecking the place. That disconcerting track with the screaming and creepy laughing he dropped about two thirds of the way through. But mostly the crowd. They are absolutely loving it - never before has Belfast witnessed such a joyous combination of rave and fun.
