It was indeed another compelling music documentary from BBC4, the subject of which was always going to be of interest here. That early adoption of synth tech set the course for the dance music exlposion towards the end of that post-punk decade - the Eighties.

As Para said, it was maybe mis-named concentrating as it did on the bands more than the technology, but nevertheless it was a sumptious trip down memory bank. 

I remember going to see Depeche Mode's Construction Time Again tour in Bristol and being blown away by all the new and unique synthesised sounds, if not necessarily the songs themselves. It was a brave new wave, perfectly post-punk and pioneered, with the exception of Kraftwerk, on this very Isle - much like what went immediately before and after. How the hell else could the transition between punk and dance have been made?

... seeing all those kids in the late 70s/80s being like WTF is this made me realise that because electronics/sampling now allows any kind of noise there's not going to be another quantum leap in music, is there?

Perhaps wait until Quantum Theory gets applied to music making!
