Believe it or no,t before Gramatik was part of Grizmatik and/or releasing on Pretty Lights Music, he was a throwback ’90s golden age hip-hop beatsmith. Numbers like Street Bangerz Vol. 2‘s “Chilaxin’ by the Sea” endeared him to thousands of fans around the world as his boom-bap percussion, jazzy piano licks and breezy summer beach vibes transported us to another world. This week, more than a year after Volume 3, Gramatik has unearthed 22 unreleased cuts to put together Street Bangerz Vol. 4.
