Psychogeographers listen up. Another opportunity to see Align presents itself at the Museum of London on 25 August. If you're into wacky theories about London's history and development or enjoy fondling books by Iain Sinclair and Peter Ackroyd, then this is a must-see. Robert Kingham (vocals) and Rich Cochrane (sound effects) have developed a two-act narrative that weaves together London's ley lines, mysterious mounds and local history into a hugely enjoyable show. If you only see one arcane travelogue connecting ancient monuments to the vinegar trade this year, make it this one. Align is at the Museum of London on 25 Aug, 6-8pm. Tickets are just £5.
