A　Jazz Concert

A few days ago, I went to a jazz concert which my friend sang and played the piano at. Her husband was on guitar. Their play concert (play is when there are actors who play out a story, think Shakespeare) was very nice. I thought a good performance has a good communication.

Last sentence I'm not sure the meaning you are going for. It sounds like

"I think a good performance has good communication with the audience"

  - I would take this as meaning, the band must communicate with the audience, talk to the crowd, try to interact with the audience instead of just playing one song after another.
