Some of the most beautiful, era-defining music has been co-composed by Karl Bartos. 'The Robots', 'Computer Love', 'Neon Lights', 'Tour De France' and Kraftwerk's 1982 number one single 'The Model' all contain his deft musical touch. For the first time, in The Sound of the Machine, Bartos speaks candidly and with wit and humour about his life in Kraftwerk, a band widely acknowledged as being one of the most important in modern music.

In The Sound of the Machine, Karl vividly recalls what it was like to be in the Kling Klang studios during recording, describing the process and perfectly capturing the joy and passion of three people composing and recording. Now, with a successful solo career of 30 years, Karl Bartos recalls his post-war childhood, the amazement he felt on first hearing The Beatles, his first bands, his parallel career as a musician and teacher, his years with Kraftwerk, and his hopes and fears for today's musical culture.
