- Artist: Dubkasm Meets Iration Steppas
- Format: 12" Single
- Release Date: 11/11/2016
CM4400 EP is a heavyweight double EP typical to Dubkasm's forward-thinking tribute to soundsystem dub, and the hardware that shaped it. Named after the Soundtracs CM4400 console in the duo's Bristol studio (and with artwork based on the original 1986 manual), sides A and B are deep, brooding synth instrumentals, showcased at the Deep Medi Boiler Room set, and reminiscent of greats like Dread & Fred and Sound Iration. Sides C and D feature very special remixes by Leeds digital legends Iration Steppas, with an extra remix of Dubkasm's killer 10" No Retreat (2012). The second 12" is unmistakably the work of Mark Iration: filled with growling filter bass and siren-like keyboards, year 3000 style.
