It's 'Textured Covers' day on Sundays.
I've always been amazed by the creative efforts put into record covers. It must be very expensive and cut into the profits for sure. But obviously, these artists didn't give a damn about that for we all know that a 'true artist' wants to create a work of art not concern himself/herself with minutiae. The record was a complete package: The music and the cover--a multimedia work of art.
Freur was a good example. Long before "The Artist Formally Known As Prince" or Prince, adopted a symbol in lieu of a name, Freur was known only by the snake-like squiggle you see on the record. Later when they signed with CBS, the record company insisted they adopt a pronounceable name: Freur.
The Band consisted of Karl Hyde and Rick Smith who formed the Squiggle (i.e. Freur) as an art school collaboration and then later went on to found the successful electronic act: Underground.
