You can hear black midi’s rehearsal space from the other end of the road. A rhythmic racket blasts from behind the iron lion knocker on the door of a dilapidated Georgian townhouse in south west London. It’s only when they’ve finished playing that they can hear it bang and let you in… Inside, the energy only lessens a notch. Geordie Greep, black midi’s curiously voiced singer, and guitarist Matt Kwasniewski-Kelvin sit with guitars on their laps, occasionally flickering out riffs to illustrate a point. The repartee between the pair, and bassist Cameron Picton and drummer Morgan Simpson, is quiet but quick and laconic.
