So here's the long and short of it.

I was expecting an underwhelming show but Slash and Axl absolutely kicked ass.

Slash made some minor mistakes but his solos were inspired and his notes and bends were on point. Axl was smiley, chatty, and fierce. He showed some gruffness in his voice tonight and hung in there until late in the show when he started getting fatigued.

He started to fade around "Civil War" but before that each time he made mistakes it seems like he was determined to make up for it. Some trademark Axl off-time moments too. But I wasn't expecting as much power in his voice. He Mickeyed and Kermited at times but again, he made up for it. If they recorded the video board and made some minor edits, this would definitely be worth a show releasing on Blu-Ray and all that jazz.

I tried to be as objective as possible while enjoying the show. Sometimes the bass and power of the sound made it difficult to hear Axl with as much detail as I like.

TL;DR: That's about as good of a show you're gonna see from GN'R in 2021 barring new music and all new setlist.
