Whenever someone says a record is "Grown Folks Music" I want to reply, "dementia is Grown Folks Thinkin', doesn't mean I want a part of either." Normally, the GFM evangelist peacocks around fanning his feathers in either defense or exhibition, associating dissent with ignorance. His sermon is "the essence, the movement." Hip-hop is . Deviation is desertion, or worse, collusion. The Fifth Column of the Four Elements. Calm yourself, padre. Like every other genre, hip-hop inevitably striated with age; its own Paul McCartneys, Luther Vandrosses, and John Teshes emerged. No, Will Smith is not the answer. There are many answers. Snoop is pioneering Gangstadult. The Roots are morphing into rap's U2, producing reliable, if not necessarily revolutionary, album after album (?uestlove being the charismatic spokesperson for the group and the cause). Kanye may become the Phil Spector of all this with this on- and off-record antics. LL is LL. And fine, Will Smith is John Tesh. A whole cadre of underground artists, who were born too late, caters to this audience, creating a hip-hop analogy to the 1990s teenage Deadheads. J-Live is part of and apart from the adult-contempo scene, employing its smoothed-out boom-bap and socially conscious themes, but replacing its vexing nostalgia with ornery gravitas.
