Saturday night I went to see my friend Adam's band (Secret Apollo) play at Joe n' Andy's Hole in the Wall in La Mesa. Great show in an interesting dive bar. Painted murals and photo collages of regulars covered the walls. The stage was slightly larger than a pie tin -- but not by much. Adam's band played first. The lead singer of the second band placed a cloth over the microphone. I asked Adam why the guy did that, thinking it created subtle voice effects or prevented cooties. Adam replied, "For insulation. The grounding isn't very good in this place. Everytime you touch the microphone you get electrocuted."
