The Vaccines played a secret show at an Icelandic hotel as part of the Iceland Airwaves festival.
The show, which took place at Kex Hostel in Reykjavik, was a surprise for the fans and involved the band playing a cover of 'Ó Reykjavík', which is a song by local Icelandic band Vonbrigði.
During the song, Árni Hjörvar - the band's Icelandic bassist - swapped places with frontman Justin Young in order to perform it.
The band chose the name Bóluefnin to perform under as it is a literal translation of 'The Vaccines' into Icelandic.
