What would drive a man to say such mean things? What pushed Pusha T to the limit to subliminally air Lil Wayne out and say f Cash Money as a staff, record label and crew? I say it was the dark track crafted by Rico Beats. The Brooklyn-bred producer’s credits include Soulja Boy and 50 Cent’s “Mean Mug” and Nicki and Lil Wayne’s “Roman Reloaded” (how ironic?), but it’s his Pusha Ton and Terius Nash collab that really put him on our radar. Armed with ambulance sounds and haunting piano, “Exodus 23:1” sounds like the soundtrack to a murder scene. It ain’t safe no more.
