GOOD MORNING: Quincy Jones, a success in every field he’s tackled, admits he’s plunging into the magazine world at a time when many mags are folding/struggling. “That’s when I like to do it,” he smiled. “I like to go against the grain.” He launches his Vibe mag Sept. 14 as a joint venture of his Entertainment Co. and Time Publishing ventures. It’s about the hip-hop generation, and, “It’s a mix of everything in the hip-hop culture,” Jones tells us. Among the stories in the first issue is (John Ledbetter’s) “White People Who Think They’re Black”–and they include Madonna, Howard Stern and Sandra Bernhard , notes Jones. Yes. there’s also a story about Ice-T–even though the current Rolling Stone leaves no stone unturned about him. … There are movies, fashion as well, adds Jones, who says Time toppers gave him a go on the project 15 minutes after he had proposed it to Jason McManus, Richard Stolley and Gilbert Rogin. “Rogin told me he’s the oldest living white-man rap fan.” T-W topper Jerry Levin gave his blessing. And the first issue has 56 pages of ads–no cigarettes or booze allowed–in its 144 pages. “We’re aiming for an audience of age 13 to late 20s,” says Jones, who admits, “This has been a dream of mine for a long time. And we’re very proud of it.” He claims, “Hip-hop is the most creative new force in contemporary culture since jazz. Its influence pervades not only music, but language, film, fashion, literature and the visual arts. It’s straight out of the street, and it’s here to stay.” … As for pix, he and Francis Coppola have been meeting on the first draft of the J. Edgar Hoover biopic, on which they’ll collaborate musically as well. “I’m learning so much from him,” says Jones.

Jones himself has two years of his music from the Montreux festivals in the can–and when he gets time (!) will put them together in an album. On the TV front, “Everything’s coming together”–and “Fresh Prince” is starting its third season. Quincy reminds, “I’ve got six kids; I watch everything carefully.” But he also sez, “Did you ever read the librettos of Wagner?
