Earlier this week I posted a review of MCASD’s current show Phenomenal: California Light, Space, Surface. Reading this, you might have thought, “Cool! Perceptual deprivation! Now I’ll know what it was like doing LSD in the 1960s and 1970s without worrying about passing a drug test at work!” Which is all well and good. But you also might have wondered, beyond the entertainment factor, why should you care. What exactly is the Light and Space movement and why is it important?
