You might know very little about Sean Born, a gruff, gravel-voiced MC from Prince George’s County, Md., whose forthcoming album, Behind the Scale, is a cinematic journey through the small Queen Anne town in which he grew up. Born tells of his struggle over booming beats from Kev BrownDunc, and Oddisee, and others.

Born’s impressive mixtape, 909 Jack BTS Pause Mix, is out today. It’s an 18-track onslaught of released and unreleased material designed to stir anticipation for Behind The Scale, which drops Feb. 14.

909 Jack is free. Listen below.
