Early synthesizers were supposed to imitate or re-create other existing sounds, but as anyone can tell you, they mostly sounded like synthesizers. That distinctive whine and wheeze captivated all manner of pop artists, from prog-rockers to classical composers to soul musicians. However, back then, synthesizers were so expensive and bulky, you needed a major-label budget and an entire studio wall to install them.

The home revolution in electronic music gear didn't happen until the mid-1970s, when miniaturized components helped bring down the price and size. Synthesizers and drum machines began popping up in many a wood-paneled basement, and a generation of novice musicians began to tinker. One particularly fascinating aspect of this period: the sound of electronic R&B, which has been captured on a new compilation titled Personal Space: Electronic Soul 1974-1984.

The new anthology revisits an era when R&B producers and singers could tape songs at home, take them to a local record plant and press up a few hundred singles. That cohort included Starship Commander Woo Woo, the science-fiction-inspired nom de disc of Kansas City DJ Omer Coleman II, as well as the astrologically inspired duo from Grosse Pointe, Mich., called USAries.

Electronic soul wasn't just for amateurs: The home-studio era also empowered veteran artists to experiment outside the confines of label- and radio-approved guidelines. Cincinnati blues legend Albert Washington can be heard trying out an early drum machine in "Shortest Lady," a single he produced for his wife, Deborah, and her band, The Astros.
