In the mid-70s, I went to a Pink Floyd concert and sat near the front -- now I had been to many other rock concerts, including Led Zeppelin -- and this was by far louder, so ear-splitting that I had to move back onto the lawn area. It was so loud I thought my eardrums were going to break. I wonder how many decibels it was and how the musicians could endure this, night after night of performing. I'm sure it affected their hearing when they got older and I'm sure many people who attended such concerts developed tinnitus. Surprising that a concert playing soft rock like ABBA would be so loud. Because I wasn't there, hard to know what it was like for me to compare.
