The festival, one of the oldest in Wales, runs from June 13-22 in the intimate setting of the famous Music Room at Gregynog, a magnificent black and white country house set in 750 acres of landscaped grounds and wooded parkland five miles from Newtown.

Three musical compositions by noted composers Ralph Vaughan Williams and Sir Henry Walford Davies will receive their world première performances at this year’s festival.

This year’s ambitious programme is the culmination of three years’ research and planning by Dr Rhian Davies, whose primary mission has been to do justice to Gregynog’s rich musical and cultural heritage.

She is aiming to recreate the atmosphere of Gregynog in the 1920s and ’30s when such noted composers as Henry Walford Davies, Edward Elgar, Gustav Holst and Ralph Vaughan Williams all visited.

The festival opens with a concert by piano duo Philip Moore and Simon Crawford-Phillips, whose virtuosic showpieces will include music by William Mathias, which was completed at Gregynog.

Other leading artists booked include tenor Andrew Kennedy and The Badke Quartet on Saturday, June 14. They will perform vocal chamber music inspired by Montgomeryshire and the Borders, including Ralph Vaughan Williams’ ’On Wenlock Edge’ and Peter Warlock’s ’The Curlew’.

Sunday, June 15 will begin with a morning meditation, which will include words and music in the style of the 1930s festivals. Widely acclaimed chamber choir Tenebrae take the stage in the afternoon with Walford Davies’ ’The Pied Piper of Hamelin’ and other music that was written especially for the Gregynog Choir to sing at the original festivals.

Saturday, June 21 is described as ’Discovery Day’ at Gwasg Gregynog, with talks, demonstrations and displays to spotlight the world famous press. The afternoon concert marks the festival debut of Classic FM artist and Baroque specialist, soprano Elin Manahan Thomas accompanied on lute by David Miller.
