So I have read a few articles about the show and I find it laughable that people Question adler's drumming ability citing his inability to play civil war. I watched the famous show where he supposedly played horribly and a part from being a little slow, his timing is on. They guy might actually be the biggest part to their sound outside of slash. I dug Sorum with the Cult but it felt so clinical with GnR. Probably the reason Axl has his hired Gun he has been using for the past decade behind the kit.
This whole thing looks like a cash grab though. Myles Kennedy might be off touring doing his own thing, here is a chance to make some serious coin. Doesn't look like Axl and Slash interact that much on stage. Punch the clock, get on stage very late, do the show, rinse, repeat.
