My friend works with him occasionally as a producer and he told me he’s actually a totally down to earth person, and he only puts on the craziness as part of his PR image. Other than that, he’s a really hardworking guy who spent years diligently producing music by himself and for other reputable artists.
He has a wife and kid now and is pretty level headed about life. He’s fully aware he’s an entertainer and does occasionally get carried away when the moment calls for it, but he’s completely conscious of this and understands his larger than life ego is part of the Kanye West experience. Does he have some insane narcissistic mental disorder? Probably not, he just likes to get excited on television like most artists and give us all the show we want. Who says artists aren’t supposed to be at least a bit eccentric?
