I watched the Superbowl Halftime show, and to me it sounded like compressors squeezing the hell out of all the vocals but that one guy that was sticking out like a soar thumb. Quieter passeges seamed to be getting through, but there seemed to be some hard ass clamping as soon as anyone started to put anything on the mic. You could hear monitors and FOH out of the unsquashed guys mic.
Honestly I was expecting to hear someone ripping out insert cables after the first 30 seconds or so, but it just went on and on....
