Keep video screens level to the audience's viewing perspective. But other than that, let the trusses go wild - have vertical trusses sitting on the floor, have some trusses at angles,
etc...if you get the magazine lighting and sound america, look at the elation ad on the back - top left corner - cool angular truss idea. Have ground based fixtures (ellipsoidals) shooting out from behind the crates and such up in to the air, maybe through the truss. Light the truss - use truss warmers (maybe led pars?). If you've got the budget to add a few fixtures, get 4 or 8 Wiedamark LED pars. You'll thanks yourself. If any of that doesn't make sense or seems vague or hurried, sorry, I just finished a
strike and I'm about to go to bed.
