The idea of audio being expressed visually does not sound contradictory to anyone familiar with light shows and computer screens that show generated colors according to the beat and volume of a song. To scale this effect up to a stage scale, consider a great vendor of attractive and effective audio visual equipment. This ranges from the small installations that effectively turn a living room into a disco or the large lights that are fit for a rock and roll concert.
Whether or not your event is a music festival or a play, having good lighting can be key to a stellar performance. Lighting can be hooked up to a vibe interpreter or can be set manually for a light show that matches the event. There is no reason for your play or performance to go without effective lighting, and large lights can last for decade.
