Christoph Marthaler fans have no doubt noticed the tall guy in the group who often plays the butler, the MC or the crazy guide (e.g. in Paperlapapp), the guy who might seem phlegmatic but who is still eminently and theatrically elegant. This is Graham F. Valentine, the Scottish-born actor who ever since he started performing in the 1970s has been part of the extraordinary adventures devised by Marthaler, the edgy man from Zurich who manages to form a choir of helpless creatures singing in soulless forums. This solo work is dedicated to Graham F. Valentine who embarks on an exploration that is unmistakably original, weird and wonderful, devoted to the lacuna, its symptoms and variations, doing so in all languages and registers, together with the cellist Martin Zeller. Synonyms for “lacuna” include absence, omission and memory lapse.
