We know the location. There is video taken of the concert from the front that matched up the muffled audio to the clearer audio that someone got at the show. There was also a voice analysis done that confirmed who was speaking. The original video came from a company with ties to Tavistock. Tavistock was the same institution that they brought Ricky Dearman's kids to after he took custody of them. You know that Christ Church thing from 2014? Some of us here know how to archive data.
