In 2014, Matthews co-founded an interactive festival, The Good Life Experience, with Charlie and Caroline Gladstone, held every September on the Gladstone estate in Hawarden, Flintshire near the Cheshire border. It is a festival which celebrates the great outdoors, with abseiling, campfires, axe throwing, foraging, talk on survival, as well as cultural activities, crafts, books and music.
Matthews won a prestigious 'St David Award' - for her contribution to culture in 2014 - run by the Welsh government, in its inaugural year, 2014. Other prize winners on the night were Bryn Terfel and Lyn Evans.
She was appointed Member of the Order of the British Empire (MBE) in the 2014 Birthday Honours for services to music.
In July 2014 Matthews was awarded an honorary degree from Swansea University.
