Consisting of two side-long pieces, Perception & Association was composed over a period from 2012-2018. Opening side A is "Time and Again", a startling work for tape and electronics which pulses over waves of interlocking spatial relationships. These elements are at once distant, even static, yet Christoph Heemann gradually propels the listener along chapters of an unexpected and further revealing sonic narrative. While the deliberate frames and events offer a specific path, even the most active listener will gain new insights with repeated spins. Side B, "The Trains", suggests not merely a travelogue, but a series of meticulously constructed episodes that reference the record's opposite side as well as the album title as a whole. In the spirit of early electroacoustic works by Jacques Lejeune, Eliane Radigue, and Jaap Vink, these new pieces continue to emphasize Heemann's ongoing filmic obsessions and firmly engage the listener with his latest cinéma pour l'oreille (cinema for the ear).
