WHY HIM His Wu-Tang Clan was ahead of its time.
WHY NOW Kill Bill wouldn't be as cutting-edge cool without his tracks.
''When it rains, boy, get wet.'' That's the advice Quincy Jones gave the RZA back in 1997, when the Wu-Tang Clan rapper and producer discovered that he was more fiscally fit than he realized. ''I didn't know I had millions of dollars,'' says the RZA, who had spent five hermitlike years ''in the basement'' working on music with the likes of Bjork and U2. So, remembering Jones' use-it-while-you-got-it counsel, he started living ''more wild and recklessly.'' Today, the RZA's enjoying the rain in moderation. ''I've been super-duper sober. I'm not into womanizing,'' he says. ''I'm not a fiend for nothing right now'' -- except maybe his music. There's the just-released solo CD, Birth of a Prince, plus his score for Quentin Tarantino's Kill Bill. And the rapper is eyeing a future in films. ''I would love to get one romantic role,'' says the self-professed shy guy. ''If I could just have the ladies cry for me one time.''
