There may be only seven colors in a rainbow, but when it comes to humans, well, we are downright prismatic. Entering its 26th year as metro Detroit’s annual diversity festival, Concert of Colors celebrates the universal language of music. During the five-day free event, performances are scheduled in various Midtown venues such as Third Man Records, The Charles H. Wright Museum, the Scarab Club, and others (as well as the Arab American National Museum in Dearborn). Performances include M.A.K.U. Soundsystem, SumKali, and Tunde Olaniran.
