At first would you watch these two videos?
The former is Parliament, which is one of the most important funk bands in the 1970s. How stupid they were! (Of course I use the word "stupid" in a very very very very good sense.) At that time sound the conditions of the cool funk band were groovy sounds and stupid fashion, lyrics and behaviors. Uncool was cool. Parliament was the most uncool and cool funk band!
The latter is Kanye West and Jay-Z, who are two of the contemporary richest Hip Hop musicians. They aren't stupid at all. They are sophisticated and gorgeous. I like Jay-Z, but he isn't uncool cool but just cool.
At the beginning of Hip Hop history they were still stupid. Grandmaster Flash and the Furious Five, the origin of Hip Hop, were stupid enough to be uncool cool. Where has the "stupidness" gone from Hip Hop?
Ah, we have LMFAO! They are soooo stupid and uncool cool.
And George Clinton, the leader of Parliaments, is still stupid now!
