I had the same reaction seeing these guys last year at Graspop. Hearing the classic Guns songs like 'You Could Be Mine', 'It's So Easy' and the absolute epic that is 'Estranged' with this line up is actually awesome. They do the music justice, and there's a lot of energy in the show and always something to keep an eye on.
I wouldn't be too quick to pay for an album from these guys, but the live shows are worth it. Specially nowadays that Axl is behaving and getting on stage on time.
Plus, fuckin' Bumblefoot! His version of 'Don't Cry' is beautiful and he can seriously shred any of the former band members under the table.
Yesterday don't mean SHIT.
