A new prize recognising the considerable achievement of a Welsh artist has been introduced this year.

The inaugural Welsh music inspiration award will be given to the singer and guitarist Meic Stevens.

Sometimes dubbed the "Welsh Bob Dylan", the 76-year-old singer from Solfach in Pembrokeshire has had a prolific career performing in Welsh and English.

The first of his 27 albums, Outlander, was released by Warner Brothers in the 1960s.

Organisers said Stevens was "a pioneer of contemporary Welsh music, and instrumental in developing the art of studio recording in Wales".
