BC-909 is a drum machine that bridges ancient and modern percussion, exploring the evolution of music-making. It connects the prehistoric rock gong with contemporary music production, highlighting the deep ties between early human creativity and modern technology.

In prehistoric times, rocks were used not only for tools but also for making music, with the rock gong being a prime example. The knapping technique, used to shape rocks into tools, parallels the method of creating music with these instruments, underscoring the shared origins of object-making and music. This idea resonates with the essence of techno. BC-909 mimics the appearance of a stone while incorporating modern technology to function as a drum machine. It samples the sound of a replicated rock gong, recreating the prehistoric soundscape through contemporary methods of instrument manipulation. This contrast between ancient material and modern function symbolises the continuity of human ingenuity, from primitive rhythms to modern techno.
