After Silo Theatre's bombastic revival of Caryl Churchill's Thatcherite era Top Girls last year comes this quietly-stylish independent revival of Churchill's earlier commentary on the patriarchal twinset of colonial and sexual oppression.
The fascinating first half is historical power analysis in the guise of twisted bedroom farce, a White Mischief precursor in an anonymous African outpost of the 19th century British empire.
White men - the masters and fathers of all - treat women, natives and children as interchangeable, "dark and dangerous": all are to be disciplined, all are to be screwed. A game of hide-and-seek becomes a curdled echo of the lovers-lost-in-the- forest scene in A Midsummer Night's Dream. Victims declare love for their (also restricted) persecutors.
Like Top Girls, Cloud 9 revels in words and length, and in Brecht's "epic theatre" tradition, we're reminded we're watching artifice: a woman is played by a man, children are played by adults, an African "native" is played by a European, in order to show how these roles are imposed straitjackets. "I am a man's creation," says Betty the privileged wife (Steven Anthony-Maxwell).
The cast of eight, directed by Sam Shore, do a very good job. Underlining the menace, Alex Taylor's spare rumbling discordant piano cuts the occasional sweetness provided by an onstage string and woodwind ensemble. Isobel Dryburgh's excellent set covers the stage with real grass and trims wild wood within straight frames as a metaphor for the characters' restrictions.
