If we were going back to the ’80s in our fantasies, we might choose a stronger lineup: Run-DMC, Salt-N-Pepa, L.L. Cool J, Stetsasonic, Eric B. & Rakim, Queen Latifah. . . Ah, but this isn’t a fantasy concert and we’re not booking it. Besides, you won’t go wrong with the real lineup at this hip-hop nostalgia show: Whodini, Big Daddy Kane, Slick Rick, Force MDs, Al B. Sure! and a few others. Just remember: It was better than this back in the day.
