Did Jay-Z have a heavier security presence than usual for Friday's Powerhouse concert by Power 99 at Wachovia Center? Local hip-hop sources say that Jay-Z was concerned over some recent beef with Philly rapper Beanie Sigel, who was dropped from Jay-Z's Def Jam label. A Power 99 spokeswoman said that she had no knowledge of any beefed-up security requests. A Def Jam publicist confirmed that Sigel was no longer on the label, but as to whether any tension existed between Jay-Z and Sigel, she said, "I don't comment on those types of things." A Comcast-Spectacor spokesman also declined comment. Sigel's lawyer, Fortunato Perri Jr., said he had not heard anything about a Beanie/Jay-Z feud.
