Bring earplugs, sometimes festivals will provide them, but just in case it might be good to get your own pair.

Definite +1 to this. I shot a rock concert for fun a few months ago (just for myself) and my watch measured an average of roughly 94 dBA over 2 hours, which would have been in the danger zone had I not been wearing protection. Even just 20 dB of protection means an attenuation by a factor of 100, meaning that it would take 25 hours for it to be as dangerous as it is in 15 minutes with naked ears.

Unless you can prove the band told them that they had to provide a credit, you may not have a leg to stand on.

Presumably, since OP has the copyright on those photos, it would be on the band to prove that they had the right to sublicence the images in this way, not on OP to prove that they did not (since that’s the default), no?

“SNR 18%” is higher at lower ISO, but is also 18% of a higher saturation point, so it’s the SNR for a higher amount of light – no wonder it’s higher. For a fixed amount of light, as in low-light situations where you might be limited to, say, f/2 and 1/100s, the highest ISO setting that doesn’t clip anything you care about will lead to less noise. (More or less depending on the camera.)

(The effect is more extreme with the EOS RP.)

Maximum DR ≠ minimum noise. The DR is higher at low ISO because the highlight headroom is higher, but the noise floor also is, and if you are light-limited, the latter may be more relevant.
