Re: Putting on a great light/video show on a low budget?
If you want a great light show you need someone working the lights. A lights guy costs money unless you do what King Crimson did in their early days where Pete Sinfield, apart from writing lyrics, also put on their light shows at gigs as a non-playing member of the band.
Obviously that would cost you a percentage of your takings but you'd have a custom-made show and, if you made no money at a gig just aimed at getting exposure (and free rehearsal), your lights operator won't send you broke. Otherwise, if you're on a tight budget, you'll have to settle for setting up a bunch of cans.
