This performance is pleasant to hear when you take it at face value. Just the Axl of today singing with his voice of today, being in tune and in time. Cool.
The worry kicks in when you realize this might be his voice's starting point on the rumoured upcoming tour, getting tired and deteriorating as the shows go by.
He will always sound decent in 2-3 songs after a break, just as he did some semi-raspy Jungle with Underwood last year.
Overall, good thing. Liked his presence and the lower-tone song.
