Seen this piece by Yes Studio around a few times but never had a full size version to post until Paddy Duke sent me this one. Very nice stuff going on here, as Paddy points out these are obviously inspired by the Prisma book covers.
"Artwork created for the UK band. Inspiration came in the form of pre-1980s analogue hi-fi equipment. Using a reductive graphic approach, multiple designs were created, colours were mixed by hand and large format prints produced at K2 Screen, London. The resulting artwork was then re-photographed and used as the basis for a sleeve and poster campaign." – Yesstudio.co.uk
