Leeds-based Unlimited Theatre came from nowhere last year, but prove that they are no one-hit wonders with this coolly stylish piece of devised theatre named after the sub-atomic particle that is the smallest amount of reality ever imagined by a human being. So small is a neutrino that its chances of bumping into another one are tiny. Which is sometimes what it feels like as a human being.
There is almost too much in this show, too many ideas buzzing around and too many strands. One part of the performance takes the form of a lecture on particle physics that becomes increasingly absurd. An air crash, the lecturer informs us, happens when the aircraft suffers an overdose of ground. Soon he is in the realm of the mad conspiracy theorist with stories of how The Carpenters were used to send messages to outer space.
This crazed lecture is entwined with the tales of four people who meet on a train: a manic-depressive librarian, a stand-up comic, his ex-girlfriend and her lesbian lover, who has been forced to assume an entirely new identity. With its themes of loneliness, what it means to be alive, identity, memory and how we store and retrieve information, this is a show that is scared of neither the intellectual nor the emotional. Its confidence is rare and not at all misplaced.
Until August 27. Box office: 0131-556 6550.
