Lately I've been rediscovering early electronic music. Long before we had techno, trance and ambient, there was a group of hearty pioneers laying the groundwork of today's modern compositions using the most archaic of equipment. One of my long-time favorite—and definitely one of the more "out there" works of the period (discovered at a trip to the library one summer afternoon when I was in high school)—is Morton Subotnick's Sidewinder.
Not really what I would call "music" per se, Sidewinder sometimes evokes the "electronic tonalities" of the Forbidden Planet soundtrack, other times a circling helicopter (especially dramatic in headphones), and other times like nothing as much as a cat's tail being pulled, this is one disk that squarely falls into the "experimental" category.
Another artist I have an incredible fondness for is Larry Fast of Synergy fame. At one time I had all his records from the 70s (many of them on clear vinyl), but so far I've only reacquired two: Sequencer and Cords. When I first heard these records again after nearly 30 years, it was like meeting old friends. Finding Electronic Realizations and Games is going to be my next project.
Much more musical than Subotnick's work, Synergy has a definite techno feel, although nothing to compare to contemporary examples of the genre. My favorite track on Cords is Phobos and Deimos Go To Mars, a very bouncy, upbeat piece that pulses with energy.
