This is a bootleg, rather than a band-sanctioned official release. Three of these songs also appear on the "Heart and Soul" boxed set (The Drawback, Shadowplay, Interzone), and the sound quality is notably better there than here. However, the sound quality of this bootleg is really pretty good; you can enjoy the music unimpeded. There is, however, apparently a pristine sounding German bootleg out there somewhere.
The final five songs constitute the band's earliest demo, from July 1977. At that point they were called Warsaw, and you can hardly perceive Joy Division in the breakneck punk frenzy. Interesting evidence of how quickly the band evolved, but little more.
Five months later, the band (now nearly called Joy Division) recorded the excellent e.p. "An Ideal for Living," which is included in full on "Heart and Soul" and "Substance." In May 1978, they did sessions for a planned RCA album, which never saw release. This "Warsaw" cd includes those sessions in full. To my knowledge, only three (of the total eleven) recordings from these sessions have been released officially (see above). Because all four songs from the "Ideal for Living" e.p. are rerecorded here (in, I think, inferior versions), that puts the burden of value of this cd on a mere four remaining songs.
And they're pretty damn cool: a crisp (vocals all intelligible) "Walked in a Line," a slower "Transmission," a fiestier "Novelty," and a solid "Ice Age." The well-known recordings of these songs date from a year to two years later, so these are quite distinctive. If you're a fanatic, you want everything on this cd. If you're simply a big fan, these four tracks are worth checking out.
