Although this ex-English teacher and recent Philly transplant may live in a different state, his aesthetics still come from the same New York mind state that produced classic lessons like “Braggin‘ Writes.” Updating old school values for a new school of listeners, the Big Apple native hits heads up on “The Sidewalks” with a clever G-Funk-era synth riff. And anyone who has taught school in the inner city will appreciate “Brooklyn Public Pt 1,” when J raps: “One class. 31 students. 32 chairs. 25 desks. I guess they gotta share.” A solid effort, J-Live stays atop the indie honor roll.
