If you’re of a certain vintage, you’ll probably remember going to concerts back in the day where the sound was terrible. I mean, unlistenable. I saw Aerosmith in the early 80s and the song was so bad, it was often impossible to know what song they were playing.
PA systems and concert sound back then were pretty crude, consisting of nothing more than a huge pile of speakers piled on each side of the stage and a bunch of amplifiers turned up to 11. There was little to no science when it came to sound reinforcement.
That, thankfully, has changed. Here’s how concert sound has evolved over the decades and why things are so much better than they used to be. (Via Sean)
