The Lunar Society, which was a monthly meeting to discuss intellectual ideas, science, philosophy etc. Their name came from meeting on the Monday after the full moon so that there was light to ride home. This was the C18th so no street lights. Lunar Society of Birmingham - Wikipedia Some big names are associated with it.And what is a blue moon you ask, or maybe you don't. It's a second full moon in a calendar month. Very important in the social calendar before electric lighting and cars etc.
Well done in posting your first recording. Hopefully the first of many.
An issue I noticed was timing - at the beginning you had a tendency to come in a beat early (too eager), and later on in the improvisation I sometimes had the impression that you were doing your own thing independent of the backing track beat. But you always seemed to end in the right place, so that was good. Timing problems are a common enough result of nerves, but I wondered if you could hear the backing track beat well enough. Maybe you should turn up the volume a bit in the headphones.
