Beat Gems: A Definitive Visual History of the Drum Machine

Beat Gems: A Definitive Visual History of the Drum Machine

Oli Freke and Kim Bjørn partner for a 336-page deep dive into the hardware that transitioned from simple timekeeping to defining modern rhythm.

Boutique publisher Bjooks is set to release 'Beat Gems' this October, a comprehensive study of drum machine evolution. Following a successful Kickstarter campaign that doubled its funding goal, the book documents the hardware arc from 1950s curiosities to modern production standards. Author Oli Freke and designer Kim Bjørn catalog the shift from early units like the Wurlitzer Side Man and Elka Drummer One to the industry-shifting legacies of the Roland TR series and Akai MPC. The focus remains on how these machines were often pushed beyond their intended design parameters to create new genres. Moving past the technical specs, the text highlights the cultural impact of the CR-78, LinnDrum, and contemporary modules from Erica Synths and Korg. It is a necessary reference for anyone tracking how rhythmic synthesis became the backbone of electronic music.
