Gone Too Far - TNT

The short runs in the Theatre Upstairs usually sell out fast, but this year the Royal Court has brought back a trio of the most popular shows and restaged them downstairs in the main auditorium. Bola Agjabe's first play is the last of these, an edgy, streetwise account of brooding black on black violence and identity conflict exposed through a series of encounters on a London estate.

Cleverly but simply staged by director Bijan Sheibani, with each scene separated by moody dance moves, it won a Laurence Olivier Award for outstanding achievement when it premiered last year as part of the Young Writers' Festival. For unaccustomed ears, the various speech patterns take a while to get used to, but it's well worth listening as belligerent, 16 year-old Yemi (Tobi Bakare) works his way to tolerance, understanding and pride in his heritage with the help of Ikudayisi (his 18 year old brother from Nigeria whose existence he's only recently found out about).

The acting is excellent – especially from Zawe Ashton's mouthy, mixed race Armani trying to stir up trouble among the boys, Bunmi Mojekwu as her sweet-natured sidekick Paris, and Tunji Lucas's likeable and culturally bemused Ikudayisi, attempting to keep the peace whilst working out where he fits into his new London home.

Royal Court Theatre, Sloane Square, SW1 (020-7565 5000). Until August 9 (then at The Albany, SE8 Aug 14-16 & Hackney Empire, August 19-23. Tickets £25- £10
