From the cover of a truly horrible 1973 record album by Christopher Scott. (The title piggy-backs Wendy Carlos’ epochal 1968
Switched on Bach, which programmed Bach on the Moog synthesizer, becoming a million-seller. Burt Bacharach composed many pop hits in the sixties.)
I assume this is based on a typeface, but I don’t know which; a bit like ITC Neon.
The “ligaturing” is quite interesting!
Comments
(Incidentally, Switched on Bach was performed, not programmed. No computers or sequencers involved.)
Take normal letters of this shape and then try to fill the areas with a rope (or wire) in one piece. It's a sort of maze-puzzle. Algorithms doing this better as a human were known at this time (e. g. for wiring printed electronic boards).
