Ywain Gwynedd, Rich Roberts, Ifan Davies ac Emyr Prys Davies ydi aelodau Yws Gwynedd. Sefydlwyd y band fel cerbyd i gigio caneuon yr albym "Codi/\Cysgu" a ysgrifennwyd gan Ywain Gwynedd dros cyfnod o 15 mlynedd. Wrth deithio led-led Cymru, datblygodd cysylltiad y band ac yn 2017 cafodd albym wedi'i ysgrifennu ar y cyd ei ryddhau o'r enw "Anrheoli". Gobeithio wnewch chi fwynhau tra 'da chi yma. Ywain Gwynedd, Rich Roberts, Ifan Davies ac Emyr Prys Davies are the members of Yws Gwynedd. The band was created as a vehicle to perform the Codi/\Cysgu album which was written over a period of 15 years. As they toured the length and bredth of Wales, the band’s bond developed and in 2017 the co-written album, “Anrheoli”, was released.
