Our company used to do a yearly Christmas party and one year they had a live band, but the thing is that everybody there wants to chat and get to know their coworkers outside of work. The live music was so loud that you couldn't even be in the same room, so everybody jammed into a side room so they could hear each other talk without screaming.

I felt really bad every time I went to the bar b/c I had to go through the room with the band, who was playing to a literal empty room. They actually were very good, too, it was just a terrible venue for them.
