I was gonna say the Wu also. There is not one wack lyricist in that crew. RZA is one of the greatest producers ever and if you throw in Mathematics, Tru Master and Arabian Knight.......

*edit*

I'm not really a Def Jux fan though. I listened to I Phantom and Lif's constant ranting about his job, wife, lack of money, kids, getting laughed at in the club, etc. depressed the hell out of me. Since then I have decided to stay the hell away from Def Jux.
