The criticism of Beyonce is justified, but criticism of the band IS NOT.
The performance was SUPPOSED to be live.
Beyonce did not show up for rehearsal with the band as scheduled. So at the last minute she decides she wants to lip synch it. So the band has to spend Sunday evening until late in the recording studio laying down the track with her.
Then the band members have to report for duty at 4 AM on Monday morning to assemble for the inauguration.
After sitting all morning at the inauguration, the band was required to assemble at 1:30 PM for the parade. They stood for three hours waiting for the parade to start. All the marchers stood and waited in the cold for that long - little kids, high schoolers, etc.
The parade was delayed for an hour or more because the luncheon went overtime due to the long winded gasbag speakers and all the time allotted to wardrobe changes, hair, make up, etc.
The band members are consummate professionals and follow orders to a T without a complaint.
There was nothing to rehearse and there was no last minute decision to lip synch since her singing of the NA had already been pre-recorded in a sound studio with the USMC band.....
As a side note, how do you expect these public performances, along with Super Bowl entertainers, to provide sound studio quality acoustics in an open air public venue? They can't, it's impossible.
