Guy and Howard Lawrence, brothers from Reigate, Surrey, aged 22 and 19 respectively, have become one of the hottest acts in British pop. They have done this by dint of being the figureheads of a genuine garage-house revival. Clubland has been embracing its goofier side for a good while, the macho wob-wob assault of much late period dubstep or the Guetta-esque trance-house cheese endemic in American “EDM”.

Various Artists: We Are One - Eurovision Song Contest Malmö 2013

Walking into the auditorium of a packed Heaven last night, we were instantly treated to the sensation of having our bodies invaded by thousands of infinitely complex machine insects. It's rare that a band can have such an instant and disquieting effect, but Fiium Shaark's music, we discovered, is as unusual as their name in many ways.

It's a truism in dance music culture that “everyone's a DJ nowadays”. It's generally meant in a flip, pejorative sense – suggesting that cheap technology means every man Jack and his dog can put a sequence of records together and the role is somehow devalued. But it hides a rather more positive truth, which is that dance culture is intrinsically participative, that the line between industry and punters is so blurred as to be non-existent, that those punters truly are easily as important as the hallowed DJs they look up to.

A mea culpa from me: I never gave Sbtrkt's records the attention they deserved. I always thought they were a capitulation, a softening of the radical developments of the post grime and dubstep generation with more traditional musicality and indie affectations to reach out to a more generalist, NME reading audience... and in a way they are – but, I came to realise, that's not a bad thing, and certainly not cynically done.

Against all the odds, I find myself going into 2012 with a strong sense of optimism. And the reason? I am a born-again rave zealot. I saw it at Outlook Festival in Croatia, I saw it at Sónar in Barcelona, and I saw it at the Big Chill where I was running a stage; participatory, constructive, creative partying, where the crowds go not just to be entertained but to plug into something bigger, to be part of something.
