While Rafael Toral’s Wave Field explored the soundscapes that could be formed using guitar tones, Aeriola Frequency applies the same approach to a rather different sound source. The record stands as one of few releases in history to have no source of sound — all of the tones used to create its two long compositions were drawn from a feedback loop consisting of two delays and an equalizer, with no actual input. This leaves “Cyclorama Lift 2” (46 minutes) and “Cyclorama Lift 4” (20 minutes) as exercises in electronic resonance — and surprisingly enough, Toral draws enough movement from his sound source to create pieces more dynamic than the typical ambient release.
