It’s probably a bit inaccurate to describe Simeon Coxe as a synth pioneer. A pioneer he was, but his musical inventions predated the widespread use of synthesisers. They in fact involved a set-up known as the simeon machine, consisting of “more than a dozen” oscillators.
When he introduced the first oscillator to the rock band he was part of in 1967, all three guitarists quit, leaving just him and the drummer, Dan Taylor. The result was a new band — Silver Apples, a prototypical electronic band, but with a rock sensibility secured by the equally experimental drumming.
They predated Kraftwerk, and their music lacks the polish that developed in electronic music over the subsequent decades. The primitive but complex set-up produced an abrasive and raw, yet repetitive and hypnotic sound.
Perhaps Silver Apples were the first post-rock band. Maybe they were even the first electronic pop music band. Their first two albums even predate 1969’s An Electric Storm by White Noise, which enlisted the help of the BBC Radiophonic Workshop’s Delia Derbyshire and Brian Hodgson to help realise David Vorhaus’s futuristic electronic vision of pop.
Like White Noise, Silver Apples were met with limited commercial success in their time, only to be discovered as cult favourites decades down the line. The public just had to get used to the idea of electronic music.
