Pinned eyes stare from a frozen husk of a face as a clubber comes down, cradled high over London on a window-cleaner’s perch. Director WIZ’s 18-minute video for Flowered Up’s rave epic “Weekender” (1992) takes you on the E’d up odyssey of Little Joe (Lee Whitlock), from skinning up at work through clubland peaks to chilly aftermath.

Some rock bands base their career around being musically fluid, an ever-changing what-will-they-do-next? conundrum. Others, such as, famously, Motörhead and The Ramones, simply go on doing their thing, honing it, repeating ad infinitum, with an almost zen devotion. The results, at their best, are vigorously on-point.

The Orb’s story is rooted in the widescreen psychedelic explorations of Pink Floyd as much as the MDMA-fuelled musical adventures of acid house. This is music to get high to, laced with all the effects, from distortion to reverb, that play with the mind and take it on a trip.

Just before the encore, the crowd is finally warmed up and dancing. It took a while, but hands are now in the air, middle-aged bodies are shifting about, muscle memory of MDMA nights in the last century.

Ageing boppers may bristle at the idea of a dance album where the average track length is three minutes. Yet this, Sonny “Skrillex” Moore’s first solo album since his debut nine years ago, is the most groove-based thing he’s done.

Orbital, one of the great electronic dance acts, had a run of albums during the 1990s that encapsulate that decade in the UK (at least, for those willing to ignore the historical revisionism around tired, retro-tastic Britpop by the same media "arbiters of taste" who invented it).

Carl Cox is one of the key DJs of his generation, the generation that propagated the club culture which blossomed from the European acid house/rave scene (and originally, of course, from black American house and techno).

The Oslo World organisers are at pains to point out that, despite the name, they are not a “world music” festival. And with good reason, really. There may have been a few familiar WOMAD veterans headlining over the week-long event – Senegal’s Youssou N’Dour, Malie's Fatoumata Diawara, the queen of Cuba Omara Portuondo – but the emphasis was emphatically not on any kind of beads-and-bongoes authenticity.

There is now a kind of “leftfield mainstream” in electronic music. It’s populated by people a decade or more younger than the original acid house generation, but who take their core inspiration from post-rave experimentation of the early-mid Nineties. Dusky, Bicep and to an extent people like DJ Seinfeld, Four Tet and Jon Hopkins all channel the rich melodies and textures of Future Sound of London, Orbital, early Aphex Twin, Underworld and co to arena-filling effect.  

The journey of Ross “Hudson Mohawke” Birchard has been truly one of the most extraordinary in modern music. From teenage scratch DJ champion and happy hardcore raver in some of Glasgow’s more feral club environments, in the late Noughties he quickly moved through making rhythmically fractured hip hop.
