Alicia Keys and Jay-Z
New York's historic Carnegie Hall is hosting its first hip-hop series this week: a pair of performances from Jay-Z to benefit the United Way and the rapper's own Shawn Carter Scholarship Foundation. He took the stage last night (Feb. 6) and will do it again tonight, tapping special guests like Alicia Keys (pictured) to up the ante on festivities.
