Contact the label, or have an attorney contact the music label. Inform them that you'll be sending a cease and decist letter to the label (a formal one) over non-payment of work for footage you shot. You're the primary copyright holder until paid, and until then, they're distributing content which does not belong to them. Inform them you'll be filing a copyright takedown notice to the platforms steaming the music video (YouTube, Facebook, VEVO, etc) and will be seeking to recover revenue made by the video's syndication, or they can pay you the fee you invoices the bankrupt production company.
They'll pay you, and then they'll sue the bankrupt production company. But you'll be paid. Screw them.
