Listening back to the sounds one has recorded is pleasurable and meditative, too. When detached and disassembled from the reality of the then-present, sounds have yet another story to tell.
Cultivate it in its many forms, fried, deep fried, wet and dry, plain and flavoured, happy and sad, fierce and tender. All the many shades of sound that exist must be within reach.
Surefire because, guaranteed, no-one else has done it yet. Which means its easier to set your own rules.
