Few emcees are smoother than Epiphany (above), the Pine Bluff-born, Stanford-educated purveyor of literate hip-hop. Even fewer rappers can sound on task over grimy street beats one minute and fresh over smooth, jazzy tracks the next. We like it all, but prefer the latter, which is why we're keyed up for "The Jam Session," a night at the new Mediums Art Gallery that has Big Piph on a mic alongside Gina Gee, local soul diva extraordinaire, and marks the return of their always-tight backing band, One Night Stand. Another great R&B songbird,Stacey Avery, opens. Also, Seanfresh, Osyrus and Rodney Block are billed to drop in with the band. It's being billed as "live music for a mature, kickin' it crowd." Sounds right down our alley.
