A two-play edition featuring Anthony Neilson's companion plays, The Wonderful World of Dissocia (2004) and Realism (2006), both produced by the National Theatre of Scotland.

Produced originally for the 2004 Edinburgh International Festival, The Wonderful World of Dissocia wowed critics and audiences alike. This is a hugely original play, both magical and moving, that confirmed Anthony Neilson as one of major voices in contemporary British Theatre. The entire original cast and creative team have been reunited for this keenly anticipated revival.

Lisa Jones is on a journey. It's a colourful and exciting off-kilter trip in search of one lost hour that has tipped the balance of her life. The inhabitants of the wonderful world she finds herself in - Dissocia - are a curious blend of the funny, the friendly and the brutal. As Neilson himself put it, 'If you like Alice in Wonderland but there's not enough sex and violence in it, then Dissocia is the show for you'.

Realism premiered at the Edinburgh International Festival in 2006. It follows the life of one man during an ordinary day but veers off from the commonplace to become a deliriously surreal trip inside his wayward imagination. It was described by the Guardian as a 'bold and utterly distinctive all-singing, all-dancing show, like nothing else you'll ever see'.
