This is a High Quality Stretched Time of "Time Forest", the 4th song from the album "Soundscape 1 : Surround" (1986) by the master Hiroshi Yoshimura.
"If Surround can be listened to as music that’s as close to air itself, allowing us to enter each listener’s sound scenery, or as something that exists within a new perspective, expanding the middle ground between sound and music, and transforming it into a comfortable space, it would be much appreciated".
— Hiroshi Yoshimura
Originally released as an album in January 1986, Surround was recorded by Yoshimura as a commission from home builder Misawa Homes, intended to function as an “amenity” designed to enhance the company’s newly built living spaces.
In his original notes for the album, Yoshimura recommends that Surround be placed in the same family of sounds “as the vibration of footsteps, the hum of an air conditioner, or the clanging of a spoon inside a coffee cup.” And, as he suggests, “with the addition of city noise from outside the window,” you may hear Surround in a completely new way.
