Omaha-based Acass Systems is revolutionizing staging for live music
Co-founder Cass designs staging components to custom specifications for artists. For example, Acass Systems was responsible for the riser on which Mick Fleetwood’s drum kit was set up for Fleetwood Mac’s tour that stopped in Lincoln on Jan. 17. The firm also designed the support structure on which the stage-width LED display was mounted.
