With their collaborative debut just three weeks from release, Philly rhymesayer MarQ Spekt and Manhattan-based beatsmith Blockhead have unleashed another single off the eagerly-anticipated set. Coming on the heels of mid-June’s SumOfItsParts, Grilchy 808 trades its predecessor’s boom-bap sound for something even, well, grilchier. (According to Spekt, “grilchy” is grimy and filthy combined.) Over Block’s pitched-down samples, ambient synths and lurching drums, Spekt delivers fast-paced, wordplay-heavy bars destined to strike fear into his competitors’ hearts. Feeling it? More awaits on JustPlayWitIt, slated to drop July 29, via HiPNOTT Records.
