Two-thirds of one of the best summer jams in recent memory reconnect on Polyester’s “I Wish.” Rather than evoking feelings of sunny days and cookouts, the Freddie Gibbs-featured track has the vibe of a dimly lit house party. You can almost see smoke wafting around a modest apartment as the bass rattles and pisses off neighbors in all four directions. “I Wish” is the first single from Polyester’s new mixtape, P.O.P. (Passion, Obsession, Profession), which hits the net next week. Look for it to be packed with plenty of playlist gold.
