Re: Less stage lighting
Both of the effects you're asking about was simply achieved utilizing specific hang positions/locations of the lights. Chances are with the dancers being lit yet not the
stage, lights were hung on booms in the wings (generally on both) sides of the
stage. Fixtures were likely placed a 1-2 feet off the
deck focused across
stage so that the beam is relatively parallel with the
deck. Of course, fixtures would generally be hung higher up on the booms for various angles, but the general concept would be the same.
As far as the gobos, these were likely hung as top light or even possibly back light so that they would be able to adequately
cover the
stage with the
pattern, but yet the fixtures (if the beam hit the dancers) would be from the top or back of the dancers and would not be discernable by the audience.
There are numerous variations to this, but this is generally how those lighting designs are achieved.
