Though long celebrated for his work in indie-R&B group the Internet and with the likes of Kendrick Lamar and GoldLink, Steve Lacy went stratospheric this year after TikTok sent Bad Habit, a single from his second album Gemini Rights, to No 1 in the US and No 8 in the UK. The attention has brought his excellent mix of funk, R&B and slacker rock to a whole set of new ears. Case in point: armies of bright-eyed teens descending on London’s Roundhouse on a Monday night, braving a freak bout of snow to see the Los Angeles-based guitarist, songwriter and producer perform Gemini Rights’ surly tales of heartbreak and heady sex at the second of two sold-out London shows.

Their phones are at the ready before Lacy even hits the stage – a given, considering his core demographic. When he does appear, it is clear that they’re right to have been eager: Lacy is an arresting presence and madly handsome under ever-changing mood lighting. He shows off a tongue-in cheek sense of humour, quipping about messing up his own lyrics, about his fans and his previous shows: “This is one of the craziest tours this year – we laughed, we cried, we smashed cameras,” he says, cheekily referring to an onstage bout of frustration in New Orleans.
