Rappers are not traditionally noted for their reliability. Even the most decorated of hip-hop acts tend to arrive late, skimming over albums and grumbling about curfews. So the pre-advertisement of Joey Bada$$’s precise stage time, faithfully adhered to by the 19-year-old Brooklynite, served both to surprise and set the tone for a set which packed much into an hour.

Jo-Vaughn Scott’s debut album, titled after his stage name, is not out until January, but he drew heavily from 1999, his critically-adored mixtape throwback to the genre’s mid-90s golden age.

His quickly set-out signature was a call-and-respond shout-out in honour of the collective he founded, Pro Era, and by the time Scott arrived at World Domination, with its fuzzy piano backing and playful cartoon sampling, the singer barely needed to dole out his own chorus, echoed around the sold-out Concorde 2 by a crowd in sync from the start.

Kirk Knight, a livewire comrade of Scott’s in Pro Era, joined in halfway through, but even the break his beatboxing afforded could not save the main man from ending up drenched in sweat. Stretching every sinew, Scott’s wordplay suggested much more in the offing from a star with an incessant sense of urgency.
