The texture and grain difference between the two is subtle but it shifts the whole mood. The right version reads slightly more worn, which works well for Dark Side of the Moon.
I really like how the light version looks, but it has some legibility issues. Since readability is more important for users than visual appeal, I think the dark version is the better option.
BTW, I initially voted for the light version, but after analyzing both options more closely, I changed my mind 😄
