Whilst Field Day has always attracted an astounding array of acts, this year promised to be something truly special with Aphex Twin's headline set at The Barn. A new stage for this year's event, it's as though it has been purpose built for the headliner. A huge, hangar-like space with numerous entrances, it's capable of holding an audience almost equal to that of the open-air main stage. We're also promised better sound and a spectacular, state of the art light show, befitting the legendary producer.

Fortunately, when the time came, Aphex Twin did not disappoint. His two-hour set was an auditory tour-de-force, pulling from a wide range of electronic and dance music genres to deliver an inventive, intoxicating selection of tracks that turned The Barn into a sweltering dancefloor. Under a sea of laser lights, the audience were swept along, dancing as Aphex Twin (unseen by most of the audience) directed the evening.

With such a huge name headlining, it was no surprise to see much of the day's lineup coalescing around similar genres. Stages from Resident Advisor, Fact, Bugged Out and Moth Club offered up dance from the likes of Joe Goddard and Fatima Yamaha, or innovative electronica from Kaitlyn Aurelia Smith and Flying Lotus, that seemed tailored to guiding the crowds through the day in a heady whirl of beats and bleeps.

It was only by venturing further from The Barn, towards the East end of the site that the lineup shifted dramatically. The main stage served up a mix of pop and indie, culminating in a hip-hop double-header from Lady Leshurr and headliners Run The Jewels. Shacklewell Arms, meanwhile, offered an impressive alt-rock line-up with Kevin Morby, Thee Oh Sees and Flamingods, whilst Crack's stage offered more eclectic fare with John Cooper Clarke, Death Grips and Slowdive.

Kaitlyn Aurelia Smith kicked things off with an early afternoon set on the Resident Advisor stage. Her transcendent compositions marred only by a little too much bass, losing some of the detail and intricacy that made Ears such a wonderful record. Otherwise her set was fantastic, with some truly gorgeous visuals of shimmering crystalline forms to accompany the music.

Audio-visual spectacle is common theme on the Resident Advisor stage with both Forest Swords and Flying Lotus using visuals to great effect. Matthew Barnes led us on an atmospheric journey through cuts off of Engravings and his latest record Compassion accompanied by a series of videos depicting dancers interacting with nature, which helped to build a thematic thread through the set list. Flying Lotus, meanwhile, brought his iconic projections for his headline set on the stage, performing pieces from You're Dead, Until The Quiet Comes and Cosmogramma as well as a surprise remix of the Twin Peaks theme.

Over at the other end of Victoria Park, Death Grips led a packed Crack stage through a raucous and thrilling set that pulled from almost all of the band's discography. The Money Store cuts 'System Blower' and 'Hustle Bones' garnered the biggest mosh pits of the day, with only 'Get Got' disappointing due to a rather chaotic pace that left the performance of the song largely incoherent. Later at Shacklewell Arms, Kevin Morby played a beautiful, late afternoon set that would have been for many in the crowd an exciting first glimpse at material from City Music. Whilst new track '1234' brought a Ramones-esque energy to the set, it was in Morby's quieter, more contemplative moments that his performance really excelled.

After all this, Aphex Twin's incredible set was simply the perfect way to end the festival. Throughout the day it had felt as though everything had been building to that one moment. Wandering through the crowds, you would spot Aphex Twin's logo almost instantly; on t-shirts, or bags carrying an exclusive 12" single, or even crudely inked onto skin. Entering The Barn shortly before the set starts you could feel the anticipation and excitement and when the music finally started, it was as though the audience was lost in reverie. There were no words from Richard D James, none needed to be said. He had gathered us together for the party of a lifetime, and he delivered.
