Bryn Terfel will return to Llangollen

And he will share the bill with a good friend who is also a world class tenor.

The popular bass-baritone will be the star of the evening concert on July 7 next year, alongside Maltese opera colleague Joseph Calleja, whose voice has been compared to the legendary Caruso.

Tickets will go on sale on Monday.

Acts already confirmed include mezzo soprano Katherine Jenkins, who will perform a concert adaptation of Georges Bizet's opera Carmen on the opening night.

Jools Holland and his Rhythm and Blues Orchestra will bring the curtain down on the festival on July 10.

The Wednesday night concert will be a celebration of musical theatre featuring Kerry Ellis, dubbed the First Lady of the West End, and the musical theatre boy band Collabro who won Britain's Got Talent in 2014.

Terfel, who took to the Llangollen stage to celebrate the Eisteddfod's 60th anniversary as well as starring in Sweeney Todd two years ago, said Llangollen is a unique festival.

"The Llangollen International Musical Eisteddfod is a wonderful event and I'm grateful to be given another chance to perform on stage there again – and the fact I will be joined by Joseph Calleja is an absolute dream come true."
