Issued on Fat Beats Records, Absolute Value finds Boston MC Akrobatik rallying a who’s-who of underground and mainstream rap — Talib Kweli, Chuck D., B‐Real, Mr. Lif and Little Brother among them. Rooted in boom-bap and conscious hip hop, the CD pairs punchy drums and urgent lyricism with guest turns from Bumpy Knuckles and Brenna Gethers, balancing battle-rap grit with politically minded bars.
