Performance poetry, I am told, is the new rock ’n’ roll. Poetry nights may vie with comedy at venues up and down the country, and a new generation of twentysomething urban poets and rappers are certainly strutting their stuff, but I’m yet to be convinced that it’s the burgeoning success that promoters would have us believe. Still, the first of two Pop-Up Poetry evenings of “poetry stand-up style” in the upturned purple cow on London’s South Bank gave me a chance to sample some of the artform’s best-known performers, and it confirmed my view that it’s a very mixed bag in terms of style, content and quality.

Ben Drew, who records as Plan B, is busy on the promotional rounds. He has spent the day at the BBC's Maida Vale Studios being interviewed by Fearne Cotton and others for TV and radio, and performed his new single "She Said" as well as an ebullient cover of Charles & Eddie's "Would I Lie to You?" He's accompanied by a nine-piece band, including three gospel backing singers, and is as sharp-suited as the promo photos you see here.

Hip hop is the new ballet. Instead of mostly girls in tutus, mostly boys in tracksuits; instead of pointe-shoes, trainers; instead of arabesques and fouettés, handstands and windmills; above all, instead of nice, nasty. The smell on stage is burning rubber from the shoes; the atmosphere is electric; lights fractured; discipline razor-sharp. Some armies and ballet companies would crawl over broken glass to have the ensemble unanimity that’s displayed in Boy Blue’s cracking show Pied Piper at the Barbican.
