Radiohead’s interactions with San Francisco have been overwhelmingly positive (if you discount sound interruptions at the first Outside Lands fest, of course). I’m excited to see that their artist collaborator Stanley Donwood is having his first stateside show, “Over Normal,” at Fifty24SF on Fillmore starting tonight. Following a reception tonight, the work that plays on text-focused ads in primary colors will be viewable through the end of October: “The catalyst for the large works featured in the show is Los Angeles, where Stanley began to notice (with equal parts amazement and distress) that the advertisements bombarding him on the multilane highways were made of seven basic colors, immediately grabbing viewers’ attention in a primal way…Stanley noticed a parallel between the use of those colors and an influx of spam emails that promised everything from more fruitful sex lives, to cheap foreclosed properties at the expense of someone else’s misery. ”
