Civil Defense" was—and still is—a tone poem. It was written in 1984 and first performed in various beatnik-esque coffee houses (with a simple beatbox) in and around Chicago. It is considered to be one of the earliest vinyl releases of House Music. The LDdlm edition of the original recordings documents the enduring legacy of this iconic piece of audio history, including the long lost Ron Hardy edit and a reshape of the edit of Ivan Smagghe for the first time on vinyl.
