The FleetCenter in Boston welcomed a number of today's biggest hip-hop acts to town last night (Oct. 29) as radio station WJMN (Jam'n 94.5) hosted Monster Jam 2001. The event, sold-out well in advance, featured appearances by P. Diddy, Eve, Missy Elliott, City High, Craig David, Fabolous, and Nate Dogg, as well as long-dormant trio Bell Biv Devoe.
