The effect of good lighting at any live concert shouldn’t be under-estimated. At The Black Keys’ New York Terminal 5 show the light was like purple paint poured all over the punters.
The purple lighting was dominant pre-show and between songs. Songs were dominated by other shades and the general stage lights and bright strobes.
Such a simple lighting technique seems to have a bonding effect, instantly there’s a unifying force other than the band. It’s mood setting and pacifying to a degree. It softens the harsh concrete angles of the venue and no doubt a few attitudes.
To see this light and the simplicity of its other-wordly effect it’s surprising it’s not utilised at more shows or by more bands.
As an aside, check the bald-headed dude going nuts in the video. The lights, the lights! They were clearly too much for him. This footage was shot after the main set and before the encore.
