The duo played the Pyramid Stage on Friday.
The Brighton-based pair have been having a rollicking time of late, enjoying a killer set at Glastonbury (read more about that here) and seeing their sophomore album hit the album charts at No.1.
Their headline UK and Europe tour, joined by At The Drive In and Black Honey across all dates, will see them play shows in Cardiff, Reading, Manchester, Leeds, Birmingham, Glasgow, Nottingham, Dublin, Bournemouth and Brighton.
After selling out the first London show at Alexandra Palace on 20 November, the twosome had already added a second date; and now a third date has been confirmed for Wednesday 22 November 2017.
