Thundercat @ O2 ABC, Glasgow, 14 Nov

Walking onstage to eye-roll inducing chants of "here we fuckin’ go", Thundercat is literally dressed to stun. If you’re at all familiar with the R'n'B-slash-jazz bassist, seeing him enter the O2 ABC donning a polychromatic sequinned jacket and baggy red shorts should have been the least surprising moment of a marathon set. “Y’all ready to travel down a rabbit hole?” he asks. The audience respond with cheers and hollering, obviously, but they have no idea that when Stephen Bruner says he’s taking them down a rabbit hole, he really fucking means it.

What starts as a fairly conventional set melts into a woozy sludge of hypnotic instrumentals, more akin to a jazz show than one might expect. There’s a noticeable lack of structure to the evening, mostly for the better, with songs often running into one another. Backed by a terrific touring band, it’s when Bruner just does his own thing on his signature six-string bass that the set is at its best. The addition of an electric violin, in particular, invigorates fan-favourite tracks with just the right touch of oddball vigour.

With a (mostly collaborative) back catalogue as extensive as Bruner’s, even the 90 minutes he’s onstage seems insufficient. Halfway through performing Bus in These Streets, he takes a moment to give a shout out to friend Kendrick Lamar, before integrating These Walls – a track he worked on for Lamar’s To Pimp a Butterfly ­– into the performance to rapturous cheers. He seems to thrive on spontaneity, and unexpected moments like this keep what could have been a slog of a set compelling.

It’s Thundercat’s irreverent humour that made Drunk such an infectious listen, and in a live setting it’s magnetic. It’s so easy to forget what a world of difference it makes to a live show when the artist is visibly having fun performing, and seeing Bruner beam whilst singing about cats is heart-warming in a wonderfully surreal way. “If you know the words join in,” he tells the crowd, conjuring forth a collection of melodic meows from the room. That says it all, doesn’t it?
