Fritz Enkel's "Psycho- Und Elektroakustik Der Schallbildsynthese" from 1958 documents a pivotal moment when electronic music was still finding its sonic language. Released on Gravesaner Blätter, this record captures Enkel's systematic exploration of sound synthesis—how acoustics behave, how the human ear perceives them, and what happens when you push electronic instruments into unfamiliar territory. The pieces move from psychoacoustic investigations into the mechanics of perception toward pure elektroakustik experiments, each example a step in a larger inquiry. This is music as research, made with the curiosity of someone genuinely discovering what these machines could reveal about sound itself. It's a fascinating artifact of early studio experimentation, when German composers were thinking deeply about the relationship between physics, perception, and artistic possibility.
