I really like the minimalistic design of these album covers. I also admire the simple yet harmonious color schemes. They're quiet, yet very evocative. The words are very understated, which works well with these designs.
1950s. Variation on neo-concrete artist Max Bill who was a Swiss architect, artist, painter, typeface designer, industrial designer and graphic designer, who trained at the Bauhaus, under Kadinsky, Klee, and Schlemmer.
