A pair of gifted Philly emcees in STS and Truck North brings the lyrical heat on their new collaboration “Suicide.” Sampling Phantogram’s “K.Y.S.A.” (found on The Alchemist & Oh No’s compilation Welcome to Los Santos), STS taps into his accustomed, free-flowing word wizardry, handing it off to Truck North, whose confidence authoritatively seals the deal. Combining lyrical urgency with an at ease bravado, the track is helping us glide toward the weekend.
