This was above the concert Chicago, others may have seen - hundreds were there

One star trailed to the right and disappeared into light congestion.
Then in the middle of the last song three stars go racing at the speed of light to the left one chasing two, when they all got to above the mountain I saw one crash into another and both hit the last one and disappeared over the mountain into light congestion, silent no noise - the distance of stars
I was DD for my father at this concert and may have caught one on footage
They may have been disturbed by the concert, definitely not related, there was a jet following shortly before and after which promoted me to look up.
It was night and you could see other stars, but the light pollution made it difficult to capture- if it was pitch black you could have seen the impossible speed these stars were going at. It literally looked like a star battle in the sky.
A vehicle stopped on the freeway for a lengthy period of time shortly after the “possible crash” could have happened
