Kool DJ Red Alert retires from radio after four decades

Hip-hop pioneer Kool DJ Red Alert announced on Instagram that he is leaving radio after more than 40 years, with a four-hour farewell set on New York's 107.5 WBLS on Nov. 30. The Harlem native, credited as a mixtape pioneer and for bringing dancehall to mainstream radio at KISS FM before runs at Hot 97 and WBLS, says he will keep DJing events. Few DJs have done more to put new artists in front of the world.
