It’s been a minute since we’ve heard from Philly’s very own Ground Up, but they’ve sustained their momentum by dropping intermittent bangers like On Me back in October. Although this is a single, and there’s still no word on whether they’ve got a new project in the works, it’s a safe bet to say Tijuana is the start of a very successful year for the 17’s crew. Produced by none other than Bij Lincs, Tijuana displays his ability to make seemingly intricate instrumentals with a basic melody, intrinsic percussion, and a down-tempo bass line. After twelve mixtapes, it’s clear that no producer is a better match for Azar and Malakai’s vocals. Azar gets things rolling by painting a scene of him and his girl running away to Tijuana, a tropical Mexican city right on the border of California. AJ Hernz sings a catchy seemly hook, followed by Malakai’s reminiscing verse about better times with an ex, keeping the focus on getting away to paradise for awhile.
