Björk drums for Sigur Rós at Icelandic homecoming

Bjork and Sigur Ros thrilled a woolly jumper-clad crowd in Reykjavik on Saturday night (June 28) in a free concert to celebrate nature.

The open-air Nattura festival was staged to raise awareness about the impact of Aluminium smelting activity on Iceland's landscape.

The increasingly chilly temperatures did not dampen the spirits of the good-natured crowd, who basked in the super-bright sunlight as Radium – a soundscape project featuring members of Ghostigital, including Bjork's ex-Sugarcubes bandmate Einar Örn - and folk warbler Ólöf Arnalds warmed up the audience.

Sigur Ros, sporting elaborate headgear, then played a set largely drawn from their new album 'Með Suð í Eyrum Við Spilum Endalaust'.

They were joined by Bjork, who drummed on the band's track 'Gobbledigook'.

The singer then took to the stage for her own spell-binding set, despite suffering from a bad cold, which featured Einar Örn on trumpet for 'I Miss You'.

Bjork played:

'Brennið þið vitar'
'Earth Intruders'
'Hunter'
'Unravel'
'Pagan Poetry'
'The Pleasure Is All Mine'
'Joga'
'Army Of Me'
'Triumph Of The Heart'
'I Miss You'
'Bachelorette'
'Wanderlust'
'Hyperballad'
'Triumph of the Heart'
'Declare Independence'
