Ayone know the wattage used at a Rock concert?

I am glad you brought that up, Ehoehn. Spinal Tap is often overlooked when it comes to these discussions. I wonder what ever happened to that amp?

The point I ALWAYS make to audiophiles is, one venture to see live music will totally make you question the "reality" or "liveness" of a system being played at low to mid volumes. Even unamplified instruments play extremely loudly.

I thought the world record was 134 decibels by Motorhead.

I don't doubt that there are bands that are playing louder than the Who did way back when, but whether or not they make it into Guiness is another story. I also have to question how the spl measurements were taken, the distance from the stage, the size of the venue involved and the amount of bodies in attendance. All of these things will drastically alter the results of any type of measurement. Sean

Well, I never heard the Who in an indoor venue, but for my money, the loudest I ever heard (made me leave, the only time that ever happened) was Mahavishnu Orchestra ca. 1971 in CT. My ears hurt even now, thinking about it (and my brain cries out, "why o why did you stay for even 10 minutes?"

The Who's summer tour had 120,00 watts of audio power.
