the thing about UGK and Outkast, they didn't blow up huge until the late 90s, hell UGK was more into 2000...that's thanks to the attention Master P and then Cash Money brought to the south...sure, to us rap fans, we always heard of them guys, but the mainstream didn't pay attention until that silly crunk shit really started popping off.
but really, who's to say...I have a good 10 or 11 years on you, so your perspective is going to be different than mine, just as you tried to explain in that other thread about Westside Connection exposing folks your age to Ice Cube.
