Llwyfan y Maes
Pedair brings together the talents of four of Wales' most prominent folk artists: Siân James, Gwenan Gibbard, Gwyneth Glyn and Meinir Gwilym.
Their many live performances have captured the imagination and hearts of audiences with their sweeping harmonies, skilled handling of the traditional, and the intimacy of the songs they compose.
Their first album, 'Mae 'na Olau', won the Welsh Album of the Year award at the Llŷn and Eifionydd Eisteddfod last year
