Only Men Aloud tonight (Friday) headline the first of a series of concerts on the Maes as the Blaenau Gwent and Heads of the Valleys National Eisteddfod gets underway.
They will also be introducing Only Boys Aloud – a new choir made up of under 25s drawn from singing talent auditions across the Valleys.
Over 1,000 cultural activities and events will be crammed into the event in the next eight days.
