Assholes that have been quite happy Making Their Millions, along with their respective Labels, Management, Venues, Countless numbers of people they employ. And their Fans rarely complain.
So most everyone is pretty happy with the concept of an artist playing a faultless pre-recorded set/tracks except other Musicians and Dj’s.
I think you give the majority of the public too much credit.
Most people go to an event, well…just to be at the event (with the exception of some exceptional Dance music / rock or vocal artists).
Just to emphasize the point - I’ll quote another thread here…
I don’t see the crowd rioting even though its obvious they aren’t playing live do you ?
