Cold Memories is Atom Heart's contribution to Ambient City radio project realized first time in Helsinki in 1994. The original DAT-tape was compiled by Atom Heart from dubs and versions of his previously released tracks such as "Holon", "Data Haiku", "One Atomsecond" and "Ode to b.g." among others. Tracks were mixed together with unreleased songs making all together 2 hours continuous music that was devided into two parts for the double CD issue. Cold Memories is together with Aphex Twins' Ambient Works the cleanest and most crystallized samples of the ambient techno movement in Europe in early 90's.
