You've all heard a David Guetta song before. ALL of you. It's impossible to escape his particular brand of infectious pop-dance – he's essentially made his home in the top ten over the past seven years and he doesn't look likely to move house any time soon. We caught his gig at London's Roundhouse, as part of the iTunes festival, and it was as loud and hectic as expected...

The Feeling: One of the only acts at the iTunes festival to be gifted two supports, Guetta was preceded by German man-of-the-moment Robin Schulz, who predictably used his recent number one Waves to whip the crowd into a frenzy. As it was, that didn't really work – nobody was really dancing. We'll put it down to the early start and the fact that everyone was still sober. Either way, he still smashed it, in our eyes.

Next up was Clean Bandit, fresh from their chart-topping smash Rather Be, who absolutely powered through their awesome (and small, remember) back-catalogue. Vocals were on-point, drums were loud and people were finally dancing...

[related]The Look:It all went off when David Guetta appeared, especially when he immediately whipped his shirt off– at46he's still managing to make girls scream...

Aside from the central long-haired megastar, the light show and air cannons were in overdrive, creating a neat physical and visual representation of any one of Guetta's songs.

Tunes: Guettaplayed what the crowd wanted, which was essentially all his major hits, interspersed with songs that were easy to sing along to even if you've never heard them before. From Memories to Titanium, all his hero tracks were in there, plus plenty of homages to other artists.He even dropped in The White Stripes'Seven Nation Army.

If there was one problem, it was that Guetta has succumbed to the annoying tendency to build up a popular or melodic song, and then ruin it by plopping in a different song at the drop. Pretty much all modern DJs do this though. Would be nice if they didn't once in a while?

Banter: It can really be boiled down to “EVERYBODY PUT YOUR HANDS UP!” and “LET'S PARTY!” There wasn't much more than that.

Sweat Factor: On a scale of oneto 'our once-baggy T-shirt now looks like a swimming costume', then this would score a 1,000,000. We realise that that doesn't make any sense, but you get our drift, right? Incidentally, if you got our drift last night, it would have stank of sweat.

Summary: If you're going to see David Guetta, you know what to expect – lots of flashing lights, pumping kicks, dry ice everywhere, long hair, chart hits, fireworks, David jumping up and down with his arms outstretched, thunderous bass, chanting, Ne-Yo and sweat, lots and lots of sweat. You got all of that here. Well done Mr. Guetta, you gave the crowd exactly what they wanted.
