Although I took notes on each of the bands, I think I will scrap all the specific items and keep things general. Due to equipment failures, late coming crowds more interested in an unimportant NBA game, and other erratic behaviors, it was simply a little too difficult and unfair to try to come up with anything specific. I have only seen Justyn with a Y previously and have found his music to be quite good. Flo Anito is a good folk singer playing guitar and piano and I would be happy to see her again. Maybe the others if conditions are better. The venue was a decent Eritrean restaurant and bar, but was not equipped for serious musical events. In future, I may go there for a meal. The event was free, so only my time was invested. And that brings me to my theory. It is always a problem with a show when I spend my time working up graphs in my head (as Lisa Simpson once apologized..."I make a lot of graphs"). In this case, I envisioned the x axis being money spent on a show with the y axis being most enjoyment obtained with the investment factored in. If I were to plot all possible concerts (not just the ones I go to), I would get a inverted cosine pattern. Something like below. If you are not following any of this, then I am envious of zen simplicity of your thought process.
