Lawrence’s premier MCs play host to this sure-to-be-sold-out New Year’s party. Headliner Mac Lethal is a Scribble Jam freestyle champ who recently inked a deal with Rhymesayers Entertainment to release his long-in-the-making album “11:11.” Lethal’s ridiculously inventive wordplay keeps audiences entranced for the duration of his sets, which typically feature impromptu musings on life and politics. Opener Approach favors old-school funk and R&B influences in his hip-hop, while iD of Archetype takes it “next-level” with an introspective style complemented by the delicious flavors of Nezbeat. The acts begin at 9 p.m. today at The Jackpot Saloon, 943 Mass.
