Musician Imogen Heap has created a collection of six audiovisual NFTs that are carbon negative and hope to "set the bar for what digital art can and should be".
The Firsts Collection is Heap's first foray into non-fungible tokens (NFTs) and features short, improvised audio clips called Rifffs, which she created during live, collaborative jam sessions with users of the music app Endlesss.
Sold via digital collectables marketplace OpenSea, these soundbites are accompanied by swirling, kaleidoscopic visuals courtesy of Heap's longtime design collaborator Andy Carne.

Half of the profits from the sale were split fairly between all contributors while 45 per cent of Heap's earnings were donated to her Creative Passport project, with the exact breakdown listed in the description of each NFT in a bid to foster greater transparency. "In time, people could run on commission instead of running on up-front payments, which for some musicians would be really helpful," Heap told Dezeen.
"You all invest in the music together. It's interesting to be able to have that opportunity to share the profits in different ways and get creative with it."
In the hope to "set the bar for what digital art can and should be", five per cent of Heap's personal profits went towards carbon capture via Seattle start-up Nori.
