This week Rowan is delighted to chat with BAFTA-winning sound artist Chris Watson. Chris shares gorgeous soundscapes recorded in three threatened ecosystems, the Vatnajökull Glacier in Iceland, the Namib desert in Africa, and the Long Shore Drift off the coast of East Anglia. The sounds are being used in a collaboration with the Manchester Collective, to bring to life Michael Gordon’s cult work ‘Weather’. Chris was a founder member of legendary Sheffield band Caberet Voltaire, who happen to be the first band Rowan ever saw live.
