Eco, a new release for 2005 e.v., is two things above and beyond an ambient-styled minimalist composition. Firstly, it is a 'process piece', similar in concept to our first release Convergence from 1998 (reissued in 2005.) The concept of process music was originated by minimalist composer Steve Reich in a manifesto entitled 'Music as a Gradual Process' in 1968. This recording was made using a balalaika (a three-stringed chordophone instrument from the Mediterranean), a number of analog and digital delays wired in series and Space Echo. The composition was arranged using a technique Reich called 'phasing', where each discrete piece of music, or 'phrase', is allowed to overlap the same or similar pieces but are slightly out of time sync with the original, creating a slowly evolving recording that changes subtly but perceptively over it's entire course. As Reich wrote: ' To facilitate closely detailed listening a musical process should happen extremely gradually.' Both releases are designed to be played at normal or quiet levels, and are meant to be looped or played on repeat, with each piece slowly building up from near silence, growing to a quiet crescendo, and subsiding back to a whisper. Secondly, Eco, just as Convergence, was encoded with brainwave frequencies accentuated by bi-aural panning to create constructive and destructive interference in such a way as to create spatial sound characteristics so that the brainwaves should be somewhat effective even without the use of headphones, although it is most effective with them. Convergence was encoded with theta waves from 4-7 Hz to induce a feeling of calm, peace, and relaxation, to enhance meditation or contemplation. Eco plays an entirely different purpose. It is meant to be played quietly when going to sleep, and should help lull the listener into a relaxed state, and then into various deep sleep-related phases of brain patterns. More information about sleep and it's patterns will soon be available here. Since a CD is limited to 80 minutes, it cannot create a normal sleep pattern where the listener enters deep REM (delta) sleep for part of 1 hour, then 2 and 4 hour periods, but it should help bring them back down out of the alpha state which is not restful but active and taxing, and back into theta states and deep delta. And to those of you who have read this far, as always: Thanks For Listening.™.
