Music Director of the festival, Eilir Griffiths, said: “We couldn’t be more excited about the 2017 concert schedule. For the last 70 years the Llangollen International Musical Eisteddfod has brought people from across the globe together in the passionate celebration of music, dance, culture and diversity, exemplifying our values of peace and unity.
“This year’s festival will be a celebration of our history and values but also of our future, as we embrace artists and genres that many may consider not ‘traditional’ to the International Eisteddfod."
Terry Waite CBE , President of the Llangollen International Musical Eisteddfod, said: "The word Eisteddfod is the Welsh word for a gathering and that is what the International Musical Eisteddfod truly is.
"Every year since the end of World War II musicians and artists have gathered together from every corner of the globe to compete and to entertain. What makes this Eisteddfod unique is that it is all done to promote peace and harmony using the language of music."
Throughout the week there will also be live performances from emerging bands, musicians and street performers from across the globe, as well as activities to entertain the children and food, drink and local craft stalls.
