As one of the T-shirts that's a guaranteed sight every year at the Sonar festival reads: 'Fuck Berlin. Barcelona's got a beach.' But it's not just during that weekend in late June that the Spanish city rivals the German capital as Europe's centre for electronic music as - in the form of Razmatazz - it also boasts a club easily the equal of anything in its colder competitor all year round.

Or maybe that should be five clubs, for Razmatazz is really five venues in one building, all specialising in different forms of music but all with the same unparalleled atmosphere. The enormous Razz Club itself hosts indie and rock bands, as well as DJs like The Chemical Brothers and Howie B pumping it out into the cavernous ceilings, and arrayed around and above this space are the other rooms.

Lo*Li*ta has become the Barcelona base for such British club brands as Chew The Fat! and Bugged Out!, whilst the smaller Pop Bar sees them squeezing in for nights hosted by the likes of Sonic Mook Experiment and Modular Records. Meanwhile, the long stretched-out Rex Room is like a little bit of Berlin done Catalan-style, with an electro-heavy soundtrack from DJs like Alexander Technique and The Glimmers.

But it's The Loft space that has really cemented Razzmatazz's reputation thanks to the bang-on booking policy of local label Factor City, who have invited everyone from Andrew Weatherall to Richie Hawtin and Felix Da Housecat to play here. In fact, if it wasn't for the knowledge that there's so much going on elsewhere you could well stay in that room with its hi-tech sound and lighting system and spacious dancefloor well past dawn.

But that would be missing both the value and the point of Razzmatazz, for it's all the contrasts here that make the club what it is, from the glamorous sign outside that acts as a beacon in this otherwise pretty unedifying part of Barcelona and the interior decor that combines industrial minimalism with a warm edge, to the sight of the indie kids that gather here for the guitar bands getting it on to the sound of techno white labels in The Loft later on - and vice versa - as the club kids attempt to get their gravity-defying haircuts around this whole 'moshing' concept after wandering into Razz Club.

There really is something for everyone here, but the layout means it's neither difficult to find what you're looking for or accidentally stumble over something you never even knew you'd like, which Christian Smith believes is one of the secrets behind the place's success.

"The layout is wicked because it's a big club but it always manages to feel quite intimate," says Smith. "But what really sets it apart is the energy level of the clubbers. I've been fortunate enough to play in The Loft a lot and I've had some of the best gigs of my life there."
