Bryn Terfel overlooking the Wales Millennium Centre in Cardiff Bay

As the Faenol festival reaches its fourth year, founder Bryn Terfel talks about how the festival has developed and how he is determined to sign up Tom Jones.

"As long as people turn up to come and see concerts, this festival will go on and on and on," booms Terfel.

Sitting overlooking the fast-growing shell of the Wales Millennium Centre in Cardiff Bay, the world-famous bass baritone muses over why he started the north Wales event.

"I wanted people from my area to enjoy it - would they have ever heard Jos� Carreras sing for instance?," he said.

"I wanted them to say 'Whoa - I have been there'".

Terfel explained how the concerts, held over the August bank holiday at an estate between Bangor and Caernarfon, are split into three distinct evenings.

"It has fallen into this format that I particularly want to keep - the Welsh rock groups, the opera night and the music theatre night," he said.

"It is so important to keep to something people recognise and are fond of.

I tell you, I will get Tom Jones to the Faenol some year Bryn Terfel

"I feel I have given a stage for rock music in Wales."

Regular festival-goers will notice the order of the evenings has been changed, partly to fit around the busy schedule of this year's headliner Jos� Carreras.

But Terfel is also hoping the switch will avoid the muddy problems that the field found itself in last year after the Tan y Ddraig (Dragon's Fire) concert.

"The rock concert was on the Saturday night always and it used to cut up the field for Sunday night," he said.

"And now that we have put them into the Monday slot, it is brilliant.

"This is an evening I can enjoy, and I haven't been able to because of the other two nights," he added.

Hit list

Terfel has yet to finalise the programme for the event.

"We are working on a few more - I have given an idea this week of perhaps getting a band from Ireland to come - we are still open with it," he said.

Tom Jones could grace the Faenol stage in years to come

As for future years, Terfel is aiming high, and has long promised to bring a certain singing sensation to the party.

"I tell you, I will get Tom Jones to the Faenol some year.

"Of course he is on my top hit list.

"That's something that you have to strive for in some things - put it on a map and then try and achieve it.

"I have done it all through my career, so there is no way I am going to stop," he added.

The Faenol festival will run between Saturday 23 August to Monday 25 August - tickets go on sale on Saturday.
