If you take Shakespeare's Macbeth out of its political context you have castrated it. It is ultimately the twisted nature of the state and the social order which is Shakespeare's real tragedy - tragedy founded, as it must be, in a clearly articulated moral order.

Volcano, under Nigel Charnock's direction, have junked this completely, narrowing the focus down to the dysfunctional Macbeths. Through video clippings, a link is made with Fred and Rosemary West - though what illumination this link is meant to bring us is a mystery.

The Wests were so far from the ordinary that they really can't be used to explore anything but their own depravity.

Charnock, and actors Paul Davies and Fern Smith work hard to link the stories through the crime of infanticide; but because the link is so flimsy, the treatment of this appalling crime comes across as not just grotesque (I closed my eyes) but gratuitously so. Unforgiveable.

Until Saturday, 8 p.m.
