Lights and everything can be covered in this thread, but the main focus is more so the instruments etc that LP use to make the music. Lights, concert speakers, staging, video screens etc comes under the production/backline department. The band would have a say in what they get but they wouldnt care as much as what guitar they're using on what song.
You kinda lost me there at the end with the end of that post. But I do agree that lighting in the day is really hard to pull off. Arenas, night spots on festivals is where your going to have a better performance with the backing of viusal awesomeness.
LP do still do spot lights like 2004, just differently. 2004 Projekt rev mainly used long distance follow spots where you could see their shadow in the background on a set for example. These days those spotlights are on a truss line above the band. Most times before the show, you'll see about 4 guys climb up to the truss line above stage and sit in what looks like a car seat. They sit there for the entire show and operate the spotlights down on an angle so you get less shadows on sets/video screens. Ive been one of those spotlight operators before, not the best of jobs and SUCKS if you need to go toilet really bad mid show.
