I was there and this was the 5th time I've seen them on this tour. 2 vegas, 2 foxboro.
I had a blast and thought Axl sounded just fine. He used a mix of rasp and clean voice. I thought that the clean voice sounded fine, especially I t he cringe worthy spots I typically hear on YouTube videos. I'd say the only song that it really didn't work on was yesterdays.
At the end of the day, I know what I'm getting into and I thought the show rocked and the person who wrote the review in the Globe thought so too. It was well worth the $279 I paid.
Axl gave 100% - I didi see him spitting in trash bucket every song or so, not sure what's going on there.
I was there to have fun and it judge and I had a blast.
