When the troubled rap great DMX emerged as a seismic force in the late '90s, his popularity felt like a rebuke to the Bad Boy Family, the slick and flashy New York rap crew whose era immediately preceded his own. (It didn't help that DMX's Ruff Ryders label provided a new home for the Lox, the disgruntled former Puff Daddy proteges.) But DMX has come out as a special guest at a bunch of shows on Puff Daddy's current, euphoric Bad Boy reunion tour, and everyone who's seen him at those shows says he was amazing. And now Billboard reports that DMX has joined Puff Daddy's rolling late-'90s nostalgia revue full-time; he'll be on all the rest of the dates.
