In addition to being a huge fan of 1950s and 1950s jazz, I'm a huge fan of jazz album cover design from the same era. My graphic design style obviously owes a lot to mid-century modernism, the Bauhaus, and the International Typographic Style. Hard-bop era Jazz album covers, particularly those designed by Reid Miles, are some of the greatest examples of that style of minimalist design. They prove that graphic design doesn't have to be complex to be funky and soulful.
Most of the color schemes I use in my own work is heavily influenced by these album covers, even if I don't copy them directly (I usually tweak the colors just a bit).
