Synth Britannia

There is a whole series on You Tube from BBC Four, I watched them all, so good.
It turns out the JG Ballard book "Crash" was a huge influence on many of those musicians.

"In the late 1970s, small pockets of electronic artists including the Human League, Daniel Miller and Cabaret Volatire were inspired by Kraftwerk and JG Ballard and dreamt of the sound of the future against the backdrop of bleak, high-rise Britain.

The crossover moment came in 1979 when Gary Numan's appearance on Top of the Pops with Tubeway Army's Are Friends Electric heralded the arrival of synthpop. Four lads from Basildon known as Depeche Mode would come to own the new sound whilst post-punk bands like Ultravox, Soft Cell, OMD and Yazoo took the synth out of the pages of the NME and onto the front page of Smash Hits."
