Desperado and P Money—two prominent members of south London grime collective, OGz—have joined forces for a dark, dark storyteller in "Lock Your Doors". A cautionary tale of roadside happenings, it's a wholly unexpected, but brilliant effort from the Blue Borough boys. Placing themselves over a bass-knocking, wailing guitar-led production from The Heavytrackerz, the two MCs take turns to pain a picture, speaking from the wise old vantage-point of experience like true OG's, and the unpredictable air of danger played out in the visuals is only heightened by their hard-hitting flows and accompanying trap beat. At times an uncomfortable watch, the Capone-directed video for "Lock Your Doors" ends in a way that is sadly all-too-familiar in these circumstances. Watch the mini movie, courtesy of SB.TV, up above.
