I visited LA/OC area in July of 1999. From what I heard, KPWR and 92.3 The Beat were the best stations around. They were doing live mixes, playing all sorts of hip hop and R&B popular at the time along with some classic west coast tracks. I remember hearing a track on a mix show on 92.3 the Beat that blew my mind. It was Royce Da 5'9" featuring Eminem called "Nuthin' To Do". It was an underground track from then just blowing up Eminem along with a rapper I had never heard of before, Royce Da 5'9". They had their pulse on the hip hop at the time. Heard all other sorts of great tracks that weekend on 92.3 and 105.9 as well. Flash forward to 10 years later, I finally returned to SoCal in May of 2009. Power 106 was a completely different station. They were now playing pop and other stuff they wouldn't think of touching 10 years prior. 92.3/100.3 is now a rock station. I guess things change..
With that said, Power 106 and 92.3 the Beat.
