Sheltered away from the sweltering heat of the UK’s sixth(?), seventh(?), eighth(?) heatwave this year, the venues for Hackney’s Visions Festival offered air conditioned respite and intoxicating live music. Assembled across a genuine variety of locales – from the post-industrial renovated warehouse that is Oval Space, to the unassuming wooden floorboards of London Fields Brewery – is represented some of the most low-key, interesting indie rock, rap, punk, and electronic music around. It chooses eclecticism over specialism, and it works.

Opening with ALASKALASKA at Oval Space, the jazz-infused native Londoners. Their tight instrumentation and clean vocals were underscored by an always-welcome saxophone, oscillating between rambunctious grooves and sombre mood-setting. I returned to Oval Space later in the afternoon for Rival Consoles, the unassuming melodic techno producer (also hailing from London) striding on stage and diving straight in with a swig of a can and gently appreciative nod. Though textured and impactful on recording; live it, as all best electronic music does, accrued a kickdrum-puppeteering verve and tenacity, tracks like ‘Persona’ and ‘Dreamer’s Wake’ animated by Ryan Lee West’s resplendent manipulation of his live set-up.

Shifting into the basement bar recesses of Hangar for No Age, to my mind one of the most underrated rock bands of the past ten years, their shoegaze-cum-punk-cum-slacker rock niche evoked itself wonderfully through Hangar’s low-hanging ceiling. Sampa The Great owned the London Fields Brewery, her at-times-erratic, at-times-spotless vocal delivery (and live band!) stirring the crowd into a chantalong throng, groovy and political at once.

It’s actually quite difficult to express the vitality of IDLES’s performance. Anticipating the release of their second album Joy As An Act Of Resistance at the end of August, to my mind the best rock album of 2018, the set felt to my blinkered soul like a Seminal Moment, the transition – for the people present at least – from being a great band into a Great one. It’s not just the energy and slapstick and basic subversive pleasure of their performance, but the reciprocity they demand from the audience. They’re a band challenging their fans to give just as much as they do, an ecstatic communality or religious experience. One of the best gigs I’ve been to, possibly, ever?
