Hi I’ve got a movie memory I can’t remember if it was the matrix reloaded or it was some other action movie one thing I know is it’s by Tristar/Columbia pictures

anyway I saw it on DVD, it begins with a woman Giving a narration on a massacre that happened at a nightclub with really creepy intense  music what happened was these guys in suits & glasses show up and shoot the place everywhere especially a guy that was singing and it’s in slow motion and the scene is very disturbing and once it’s done the music starts playing again and the last scene I remember seeing is their in a office building talking about something in a meeting I’d appreciate the help to find it thank you
