In June 2016 Áine made her debut playing a small tent at Glastonbury, when she was spotted by the BBC and asked to perform acoustically live on their TV coverage of the festival. The reaction was overwhelming with ‘Aine Cahill’ trending on Twitter.
In 2017, Cahill was named as 'One to Watch' in The Guardian and a 'Breaking Act' in The Sunday Times Culture section. 'Plastic' won best single at Pure M Awards in August, and she would go on to play numerous festivals across the UK as well as sold out headline dates in Ireland. In October, Cahill supported JP Cooper on his UK tour.
