This was one of the funkiest shows I’ve seen for a long while; perhaps even since Prince’s peerlessly funky residence at the same venue in 2007 (though nowhere near as brilliant). There came a moment, on "Deeper Underground", when everything just clicked – the bassist and the drummer were locked in a deep groove, the guitarist was doing his precisely controlled chopping thing, the percussionist was rattling his timbales, the brass section popped and squirted, the backing singers shimmied, and singer Jay Kay himself did that weird dance, almost nerdy: glide-jerk, glide-jerk. Looking around the arena, I saw a sea of blonde highlights and jiggling bodies; the place was seething.
