I thought they sounded pretty bad as well, and the entire production
seemed pretty lame, compared to the last couple of years
I wonder, too, if part of the problem is the simple fact that it's a half
time show. No accurate way to do a sound check, since the presence of a
crowd totally alters the dynamics of any stadium. And, the performance is
so short that by the time the band and technicians warm up, it's over.
That hasn't seemed to be a problem in the last few years.
