In the absence of Power 92's annual Juneteenth concert, the RiverTop Party tries to fill the entertainment void with Sky High, a special one-off night curated by Cool Shoes' TJ Deeter and Chane “Epiphany” Morrow, the rapper and promoter behind the Chill. Both organizers multi-task. Deeter mans the ones and twos, with a mix of retro and contemporary hip-hop, while Epiphany fronts the live hip-hop band One Night Stand, one of the city's easiest bands to like. Familiar faces fill out the bill. With Epiphany, R&B crooner Sean West, who's going by Sean Fresh these days, recently put out a mixtape called “The Excuse.” To promote the CD, the pair compiled a video of 17 excuses people on the street give for not buying a local CD. It's a funny mini-documentary. Look for West to mix playful humor with earnest come-hither material. Prolific local MC Rockst*r has lately been gearing for a national push. He's toured regionally and in New York, and two weeks ago he released a crunchy, bass-heavy anthem that celebrates nightlife. It's called “1 A.M.” and he's billing it as his “national debut single.” It'll be a fitting end of the night. The party wraps up at 1 a.m.
