Mae Gwilym Bowen Rhys yn lysgennad dros ganu gwerin Cymraeg, gartref yng Nghymru ac ar draws y byd. Cadarnhawyd hyn gan ei enwebiad ar gyfer Gwobr Canwr Gwerin y Flwyddyn yng Ngwobrau Gwerin BBC Radio 2 a thrwy ennill Gwobr yr Artist Unigol Gorau yng Ngwobrau Gwerin Cymru.

Cyrhaeddodd ei albwm gyntaf ‘O Groth y Ddaear’ yn 2016 restr fer Albwm Cymraeg y Flwyddyn yn yr Eisteddfod Genedlaethol, tra bod ei bedwerydd albwm a’i albwm diweddaraf ‘Detholiad o Hen Faledi II’ wedi’i ddisgrifio gan From The Margins fel, ‘probably the most complete, bewitching folk album you will hear all year’.
