Sometimes, you get sick of heady concepts and lyrical pyrotechnics, and you just want to listen to a catchy Pop song. If you're having one of those days, you may want to hit the “back” button; despite what its title might suggest, the latest joint promo single from rap duo MindsOne and producer Kev Brown (their Booth debut as collaborators) is about as far as you can get from bubblegum. Brown's boom-bap flavored beat, peppered with old-school cuts by DJ Noumenon, sets the mood as partners-in-rhyme KON Sci and Tronic share tightly-wound reflections on consumerism, anti-intellectualism, racial discrimination and more. NYC underground mainstay Homeboy Sandman turns in a similarly sophisticated performance on the guest tip. Craving more? You'll find what you seek on the headliners' forthcoming album 14-track EP, Pillars, released yesterday to record stores and online retailers.
