Did you know that the early synthesizers weren’t really intended for rock music, but classical? How did synthesizers become ubiquitous with rock music, then?
In the summer of 1970, after popping into a pub for a pint, rock keyboardist Keith Emerson sat down at his enormous Moog modular synthesizer in London’s legendary Advision recording studio and noodled a few improvised notes. His goal was to add some electronic punch to the end of a mostly acoustic-guitar number called “Lucky Man,” written by his singer-guitarist bandmate, Greg Lake. As his fingers ran up and down the synthesizer’s keyboard, Emerson played along to the bass, drums, vocals, and guitars already recorded by Lake and drummer Carl Palmer. . .
Emerson would later say he was just fooling around, and that he definitely did not expect his first take to be his last, but Lake and sound engineer Eddie Offord liked what they heard so much, they deemed Emerson’s work on “Lucky Man” done.

That was the summer before my senior year in college and I vividly remember hearing that riff the first time, and then again and again. It was gorgeous – and so amazingly without precedent. Switched On Bach had been a wake up call – but this was new territory.
