Mammoth Beat Organ is a mechanical, modular music contraption by Sam Underwood and Graham Dunning. Designed as a two-player, semi-autonomous musical instrument, it plays unusual, sometimes erratic compositions drawing on drone music, minimalist repetition and barrel-organ-monkey techniques. Visually, the machine resembles a sprawling, partially robotic drum-kit, or pared-down, clunky fairground organ.
Debut performance of the system was at Supersonic Festival 2018 in Birmingham.
