Even though the ticket cost me over $225, I divided by 4 and to see each one of the queens. It only cost a little over $55 to see each. Promoters should package more of these multi-star shows and use my "eco-math" to market such shows. I noticed from other cities, including the Cincinnati concert, that there is trouble with the sound system in the initial minutes of the concert. We couldn't hear Gladys Knight distinctly until several minutes into her set. I'm sure the acoustics are tested beforehand but not with a test singer beforethe show begins. It's not enough for a tech to mumble testing 1,2,3 into a mike to get the full range of sound delivered.
