With their Haze Diaries Vol. 4 album only days away from dropping, Gotham Green and DJ Quickie Mart remind the world that their music is always evolving with new release Natural Progression. Behind the boards Quickie Mart puts together a beat that bridges the gap between boom-bap hip-hop and EDM-styled uptempo instrumentals, giving his partner in rhyme Gotham Green a solid foundation to build his always solid bars behind. Mix in yet another noteworthy verse from OK City veteran Jabee and you’ve got a guarenteed way to build some serious buzz for Haze Diaries Vol. 4, available for free download on August 14.
