I saw Bob Seger last night and thought the band rocked it. The sound guy did a great job as the levels were better than I've experienced at many concerts. You could hear the lyrics, the backup vocals, etc. Side note, attended a couple of shows where the sound was so bad I was wondering why I was even there.
Anyway, I as they cleared Grand Funk Railroad off the stage to get ready for Bob, I saw two guys climb up into the lights above the stage and take up position. The technical aspect appeals to me so I was wondering with all the electronic systems in place, why you would need two guys manning something up in the lights? Couldn't they do that with a camera-based system from a station back with the sound guy? Do they still man it live so the spot is on key no matter what? I'm curious.
