I don't know. But I know that I've been to several shows in the past 6 years and he sounded more or less the same in all of them.
tbh, I don't even expect a lot of greatness vocal wise from Axl Rose in 2023, I didn't even expect it in 2012 when I first saw him, but have been following closely for quite some time by then. All of this nitpicking is getting tired with time, and I used to do it a LOT on this very forum.
GnR are still able to put on an amazing rock n roll show, three hours of high energy kickass performance that transcends me into a different reality at least temporarily. I'm done measuring which note Axl hit on Live and Let Die lmao. It's just a very very good rock show. That's all.
And that's why the drone shots from the show are they way that they are.
