Try to remove yourself from mind-based listening for a few minutes each day. Start to notice when when you are analyzing sounds, but not listening to them. Listening is not analyzing, it is being with a sound fully without the distraction of the mind.
One of the problems we have when hearing a guitarist is that we analyze the performance mentally - the tone, speed, phrasing, technique, etc. There is a lot for the mind to chew on. This has it's place and is important, but even more important is the art of listening without the mind being active.
Walk in the place you live and listen without any judgements. Hear every sound clearly, but without analysis. Be full of the sounds you hear - as if they are coming from inside of you. The world is rich in sound color. Now listen to the spaces between each sound. Listen to how empty the spaces are. Notice how the space feels. Now listen to both sound and silence. If the mind interferes, listen to that as well, and then go back.
