Sigur Ros frontman Jonsi pulls headline slot at Flow Festival

The XX and Marina And The Diamonds are bumped up the bill at Helsinki bash

Sigur Ros frontman Jonsi has axed his headline slot on the closing night of the Flow Festival tomorrow (August 15).

The singer has cancelled his appearance after bassist Úlfur Hannson injured his arm while the band were on tour in Sweden. He has had surgery on the injury today (August 14).

The move means The xx will now headline the closing night in his place and Marina And The Diamonds will top the bill on the Tent Stage, with Caribou now occupying the second slot on the Main Stage.

NME.COM will be bringing you further updates from the festival over the weekend. MIA, Robyn and Sleigh Bells are set to play later.
