10 years later and Theatr Unnos is back at the Eisteddfod.

The 24 hour theatre making challenge brings theatre makers, artists, and performers together. No preparation. No plan. Just 24 hours of honest, instinctive creation.

The artists will receive a challenge on the Wednesday and have 24 hours to create something. Fast.

They will share a 30-minute piece with an audience during a fun sharing evening at Caffi Maes B on Thursday 6 August (8pm) on the Eisteddfod maes.

The artists taking part in this year's challenge are:

• Alys Letton-Jones
• Rolant Tomos
• Mark Henry Davies
• Cati Rhys
• Iza Jem
• Huw Blainey
• Roisin Ann
• Simon Watts
• Emma Mace
• Catrin Mai Edwards
• Rhodri Trefor
• Beca Llwyd
