Gwilym, who plays the piano and clarinet, has always had a passion for music. His parents Phillip and Enid both enjoy music and his older brother Nathan is a music scholar in Cheltenham. His list of musical credits include being a member of the National Children’s Orchestra, South Glamorgan Junior School Orchestra and Band and head chorister of the Llandaff Cathedral Choir. He has also taken part in Eisteddfodau and the South Glamorgan Festival of Young Musicians, where he won the junior voice competition in four consecutive years.
He was a guest at Charlotte Church’s first solo concert in London, which was televised by the BBC and is available on video, and was the subject of an S4C programme, Gwilym Evans - Seren y Gadeirlan (Star of the Cathedral). The pair had performed together while they were both pupils at Llandaff Cathedral School. This included a production of Oklahoma when Gwilym played Will Parker and Charlotte played Ado Annie.
“My voice has started to break,” said Gwilym. "I am singing tenor at the moment - I normally sing treble. Maybe I will have to have a break from singing for a while and then sing at a lower key. If I have a break I will concentrate more on the piano and clarinet.”
At 13, Gwilym won a music scholarship to Eton College.
Gwilym Evans Vocal support is provided by the London Symphony Chorus and the Welsh Male Voice Choir, and Gwilym Evans accompanies for duets of her signature song, "Pie Jesu", and "When at Night I Go to Sleep".
