A reissue of the fifth Silver Apples album, originally released on CD in 1998. Decatur was originally billed as "a voyage of pure exploration beyond the broad established horizons of electronic music. It is an adventure into perceptions of an unparallel universe all its own." Decatur consists of one track lasting just over 42 minutes - a sound collage of oscillator noises and sounds with percussion.

Decades after their influential career first ground to a sudden and mysterious halt, the Silver Apples remain one of pop music's true enigmas. A surreal, almost unprecedented duo, their music explored interstellar drones and hums, pulsing rhythms, and electronically generated melodies years before similar ideas were adopted in the work of acolytes ranging from Suicide to Spacemen 3 to Laika and Beak>. Prior to forming the Silver Apples, vocalist Simeon Coxe and percussionist Danny Taylor played in a more traditional-sounding '60s rock group, the Overland Stage Electric Band. However, Coxe's addition of a 1940s audio oscillator to the band alienated the other members so much that ultimately he and Taylor were the only ones left, and they began making music as the Silver Apples in New York City in 1967. Coxe added more and more oscillators, incorporating them into an instrument also called the Simeon that (according to notes on the duo's self-titled 1968 debut LP) consisted of "nine audio oscillators and eighty-six manual controls...The lead and rhythm oscillators are played with the hands, elbows and knees and the bass oscillators are played with the feet." Coxe and Taylor also connected with budding poet Stanley Warren, who wrote lyrics for many of their early songs, including their signature track, "Oscillations."
