DETROIT -- The last time Beck came through these parts it was Labor Day weekend, opening for U2 in the mammoth confines of Ford Field.But on Friday, July 6, the California rock raconteur made the much smaller Fox Theatre seem like just as big a deal. Opening the latest leg of the world tour supporting his latest album, "Colors" and coming on a long 50 minutes after opening act Oh Wonder, Beck and his seven-member band played a dazzling hour-and-50-minutes -- literally so thanks to the visual spectacle provided by LED screens on stage, whose parade of colorful (of course) images swirled by in 3-D depth.
