Yep its good and I'm excited for it cause I've always like AIC and have just recently started to love listening to the. DuVall isnt Staley but ya know what the same goes for The Misfits, Van Halen, Ac/Dc, and plenty of other bands after they replaced singers and they still kicked/kick ass.
I plan On going and seeing them at the Fillmore. 1100 person AIC concert, I think so
As far as it not sounding the same as it did I think you guys are just wrong. No its not the exact same but its still awesome harmony with Cantrell which is what made AIC so different sounding and great. As much as I love Lane, he was only half the unique sound of that band.
Check these out too btw. Anselmo from pantera and james hetfield on vocals for would.
