After violence in the stands forced the cancellation of a Run-DMC concert at the Long Beach Arena for the group's "Raising Hell" tour, KDAY organized a "Day of Peace" on October 9, 1986. In a two-hour special, KDAY featured Run-DMC, singer Barry White, and boxer Paul Gonzales appealing to rival gangs to stop feuding and opened phone lines for callers to describe gangs' impact in their communities. There were no murders or incidents of gang violence that day. Within two weeks, the Bloods and Crips, the two largest gangs in Los Angeles, signed a peace treaty.
