For someone who raps about rolling joints "bigger than King Kong's fingers", Wiz Khalifa seems remarkably focused. Since the release of his 2012 album O.N.I.F.C., the young Pittsburgh hip-hop galáctico has married, become a father and launched a clothing line bearing his heavily tattooed imprimatur, all while overseeing his own TGOD musical empire. No wonder Khalifa's scarecrow frame seems immune to the effects of the munchies – he never stops hustling.

That eager, entrepreneurial spirit translates into a full-tilt live show, with a four-piece backing group including a drummer and bassist, plus a brace of gigantic minders who periodically clear the stage of chucked clothing and other detritus. At the centre of it all, Khalifa gets his skinnymalink groove on, whipping arcs of bottled water into the sweatiest rows during the bumptious stomp of Work Hard, Play Hard and spurring the rest of the notably heavy-lidded audience with endless reefer shoutouts.

"I like to express myself, I like to dress weird, and I like to smoke weed!" he yells at one point, a fairly accurate summary of an extended set full of G-funk chunks and short flurries of militaristic beats. The staccato turnover of tracks and song fragments is finessed by Khalifa's constant and conscientious engagement, be it pelvic thrusts in time to the consumer braggadocio of It's Nothin or simply throwing his wiry frame into the crowd during the glowering Taylor Gang.

It is a charismatic performance, but also a more inclusive one than you might expect from an artist so obviously at ease wielding a gold-plated microphone. After a booming version of Black and Yellow, the catchphrase track that transitioned him into the mainstream in 2010, Khalifa beckons out a dozen or so of his closest team-mates to take a bow. It's hard not to inhale the positivity.
