“It doesn’t matter if you’re gay, straight or bisexual,” intones a diminutive backing singer, her voice electronically manipulated into a subaquatic masculine baritone, welcoming us to the post-gender, sexuality-blind disco future. Enter 20-year-old Shamir Bailey, a modernist Las Vegan soul-pop singer whose natural helium timbre and unaffected camp mannerisms – imagine if Prince, David McAlmont and Jimmy Somerville had a baby – render him “naturally androgynous”, without the need to concoct any flamboyance or enigma. A wannabe outsider who was nonetheless voted prom king (and didn’t go), his keynote declaration that “this is me on the regular, so you know” from last year’s breakout single On the Regular is an insouciant incitement to be yourself whatevs, and he imagines a prejudice-free melting-pot dancefloor, where every breed and stripe of human animal can twerk like no one’s watching.

He provides copious fuel. Mingling Detroit funk disco, arcade machine house bleeps, R&B soul and dashes of hip-hop, he sings of being wild, weird and under drinking age in Sin City. Make a Scene, with its lip-licking details of “crazy nights filled with lust”, is full of the jubilance of getting your first workable ID, while the MIA-indebted Youth itches as if it has shards of glitterball under its skin and teenage regrets swarming its conscience.

Plundering virtually every corner of his sole EP Northtown and debut album Ratchet to fill an hour, there are sections of I Know It’s a Good Thing and Hot Mess where he slips into the tired house formulas of the All Bar One Friday-night pulling tune. But when he climbs on to the monitors to croon funereal soul ballad Darker, bathed in swirling lights, we’re clearly in the presence of a gestating arena pro, and in closers Call It Off and Head in the Clouds, all blaxploitation funk and Prodigy squelch, he wields enough dancefloor dynamite to level the Vegas strip, Deadmau5 residency and all. It’s a pan-sexual pants party, and everyone’s invited.
