I have never heard Samuel Beckett’s voice, so I do hope that this is genuine. If it is, then it is a very rare recording indeed, as Beckett was averse to having himself filmed or recorded.
In this short clip (uploaded by Oranj Telor Theatre) Beckett reads an extract from his difficult and complex second novel, Watt, which was written “just an exercise”, while on the run from the Gestapo during the Second World War. “No symbols where none intended.”
