Most musicians/bands play live with backing tracks. “The whole set is programmed. The drummer is playing to a click. Everybody is hearing the click in their In-Ears. They’re hearing a mix of what they’re doing, and they’re hearing all of the backing tracks, and the peddle changes are happening. … They’re not using real amplifiers.”

“So there is no variation from show to show typically, unless they reorder the set.” The light show is pre-synched.

From prog metal to metal bands, to pop acts, they all do it. A lot of the old bands don’t do it. Jeff Beck, Pearl Jam, for instance. Aerosmith does. “Most contemporary bands play with backing tracks.”
