This work makes full use of echo, delay, and various other effects on the guitar, giving it a synthesizer-like quality created by a sequencer—a sound reminiscent of Tangerine Dream during that era. The repeating rhythms and gradual phase shifts create a distorted sense of time, making “Echowaves” (sample 1) a masterpiece of space guitar that induces a trance-like state; while “Pluralis” (sample 3) employs a similar technique but features a rounder, more mellow sound—this 21-and-a-half-minute sonic journey is also absolutely wonderful. It’s also impressive that this was recorded on a four-channel recorder. A true classic! (Original Japanese text by AYAM)
