The latest additions join Mumford & Sons, Fleet Foxes, Sigrid, Michael Kiwanuka, Songhoy Blues, Àsgeir, Billy Bragg, Benjamin Clementine, Arab Strap, JFDR, Kelly Lee Owens, Aldous Harding and Mammùt.

Now in its 18th year, Airwaves will also expand to a second site in Akureyri, North Iceland for the first time ever.

The festival has also announced that "due to unforeseen circumstances" Fleet Foxes will now play only one Iceland Airwaves set. The 4 November show will be the band’s only show: the set scheduled the day before is cancelled. Ásgeir will take over the Friday headline slot instead at Eldborg, Harpa, replacing his original Wednesday 1 November set.
