BBC Cardiff Singer of the World contest celebrates 30 years

The BBC Cardiff Singer of the World competition celebrates its 30th birthday this year.

Over three decades it has given a platform to young performers who have gone on to achieve success in operas and classical music, including the Welsh baritone Bryn Terfel.

The 20 finalists chosen to sing at the 2013 event are due to be revealed later.

BBC Wales arts and media correspondent Huw Thomas reports.
