Still holding out hope they'll find those pesky WMDs? While Saddam's hoard may never be discovered, you'll uncover plenty here at this showcase of East Coast hip-hop legends. The Mash Out Posse (Lil' Fame and Billy Danze) of Brooklyn's infamous Brownsville section bring their sarin-tipped ghetto rhymes and experimental rap-rock warheads. ("We the first to really get that shit right since Aerosmith and Run-D.M.C.," MOP producer Laze E. Laze recently boasted, and MOP will be doing a set each of hip-hop and metal with a full band.) DJ Scratch, beatmaker/producer/vocalist with EPMD, Busta Rhymes, DMX, the Roots, and LL Cool J, will truck in his battlefield nukes. And former Organized Konfusion MC Pharoahe Monch will envelop you in a cloud of toxic intelligence. Bring your gas mask, Geiger counter and body armor, and gird yourself for apocalyptic combat.
