But the known quantities of the first Rock the Mic Tour are plenty, really. The trek pairs two of the three highest-profile MCs of the day (that nice Mathers boy from Detroit is staying home). Even after a disappointing 2002 double album, Jay-Z remains at the pinnacle of his profession, a larger-than-life figure who's become synonymous with hip-hop. And while his shoot-'em-ups can't match Jay's storytelling, bullet-riddled gangsta 50 Cent is keeping pace chartwise with his No. 1 debut, Get Rich or Die Tryin'.
That's not even counting Snoop Dogg, whose high times and porn adventures obscure still extraordinary if limited skills. Fabolous, Eminem protégé Obie Trice, and Atlanta's Bonecrusher, meanwhile, won't get much more than their 15 minutes, but the latter -- a wild-haired hulk shouting out crunk anthems -- has show-stealing potential.
