The fourth instalment of this uniquely cultured festival is set to hit Portmeirion from September 3rd to 6th, bringing with it some fine artists such as Catfish & The Bottlemen, Jame Bay, Stornoway and Blossoms to name but a few.

Metronomy is the latest announcement and it comes a year since the release of their critically acclaimed fourth album 'Love Letters' which reached number seven in the UK charts. 'After 18 months of touring 'Love Letters' it felt like we needed to find the perfect setting for our final show, I believe we have found it!' Said frontman Joe Mount. 'We can't wait to play at Festival No. 6.'

'We're incredibly proud of the line-up this year, one of our best and most diverse musical bills to date with so much more still to be announced across the site.'
