JEEP-RATTLING BEATS BASH: The come-on was "Watch an incredible playlist come to life with special guests and performances," and the Beats Music Launch Party last night at the Belasco Theatre delivered as promised. That “playlist” could’ve been further specified as ’90s hip-hop: the talent included Ice Cube, Diddy, Nas, Dr. Dre (of course), Pharcyde, Cypress Hill, Method Man and Red Man, Bone Thugs-N-Harmony, the Geto Boys, Teddy Riley & Blackstreet, Busta Rhymes, Ma$e, Souls of Mischief, DJ Irie, DJ Jazzy Jeff and host Fab Five Freddy, with prominent Beats huckster Eminem closing the show. A Beats Music app logo appeared after every performance, carrying through with the premise. John Janick was spotted mingling with the crowd, as were Ian Rogers, Luke Wood, Julie Pilat and the rest of the Beats Music team, making sure everyone got in—but they weren’t entirely successful in their efforts. The Belasco’s listed 2500 capacity was easily exceeded, prompting a visit from the fire marshal, who denied entry to such late-arriving dignitaries as Cameron Strang and Daniel Glass. But according to our man on the scene, among those who did get in were (in no particular order) Rob Stringer, David Cohen, Steve Berman, Martin Kierszenbaum, Rob Cavallo, Guy Oseary, John Sykes, Dan McCarroll, Mike Caren, Eric Greenspan, Peter Gray, ?Julie Greenwald and Craig Kallman, Paul McCartney, Drake, Selena Gomez and Macklemore. Several of the attendees who’d come straight from the MusiCares Person of the Year event honoring Carole King said they wished they’d been able to change out of their suits for a gathering as hardcore hip-hop as this one.
