Former The X-Ecutioners turntablist Rob Swift puts together a short EP of scintillating sonic sketches that mix sweeping classical orchestration with beats from hip-hop’s golden age. “Overture” puts an interview with Swift over dramatic, apocalyptic strings, while the powerful, pavement-smashing drums and horror-movie sounds of “Principio (Remix)” are garnished with Breez Evahflowin’s grim rapping. Both “Fabric of an Orchestra” and “Boss of the Cross” find Swift unleashing his deft scratching skills on sampled cinematic symphonies.
