What’s the image that comes to mind when you think of techno? For most, it will likely be white men performing to huge crowds at festivals, laser shows and all-night clubs. What you might not immediately think of is young African-American men in Detroit, influenced by the country’s history of dance music, and playing around with drum machines and synthesizers.

Using a wealth of archive footage and interviews, Hill not only traces the history of techno music, but African-American culture and music, and how it all culminated in the creation of an utterly unique and distinctive sound. With the re-emergence of techno- and house-influenced music, there’s no better film to take you back to its roots.
