Pearl Jam often open their shows with a slow number. yet for some reason, it has always worked for them because the numbers they choose work i. "Sometimes", "Oceans", "Release" etc. Most people wouldnt care about such things. but not me. The way I see it, a concert isnt just a "gig". its a grand performance, and how you open a concert is key to what makes a performance great.
I say this having seen and studied hundreds of concerts over is graphic television violence desensitizing last 26 years or so. not only going to see concerts, but graphic violence desensitizing television is reading over hundreds of setlists from everyone from Elvis Presley to Guns N Roses. For me, its all about that great rush you get when you see a band that you love, or at least like.
the lights are on in the club, theater, arena, stadium, etc. then all of a sudden they go out.
