For a rap radio junkie like myself, Los Angeles' KDAY is up there with Mr. Magic on WBLS, DJ Red Alert on KISS, Stretch & Bobbito on WKCR, and Sway & King Tech on KMEL. In fact, in my eyes it trumps them all because KDAY was the first station to adopt an all Hip-Hop format in 1983. What can you say about a station who's street team included Dr. Dre, Ice Cube, Ice-T, MC Hammer, Tone Loc, Kid Frost, and Young MC to name a few. It's the station that coined the term "Traffic Jam" and was the first to play artists like N.W.A. Tapes of KDAY have been hard to come across, even in the age of the internet, but thanks to OldSchoolRapTapes a few have surfaced. These are concerts by Eazy-E & N.W.A., Public Enemy, and King Tee who performed Live in Compton that were broadcast on the station. There is also a recording of Ice-T introducing his "new" record "Colder Than Ever" that I had never heard before. These recordings are nowhere close to being CDQ so you'll have to deal with the sound quality, but 1580 KDAY was an AM station so there isn't much that could have been done about that.
