Just listened to it - expecting it to be going through the motions like most of their recent stuff but I was pleasantly surprised. Sure there are a few fillers but some decent tracks on there that I'll listen to again (Demon Fire has a guitar lick that's up there with their best). Not bad for a bunch of owld geezers.
They re-branded Planet Rock radio station today for one day only in honour of AC/DC and featured Brian Francis Johnson. It was very interesting, and he comes across as a very nice and humble guy.
I just gave it a listen. It's better than I expected, some pretty decent tracks but is still a bit AC/DC by numbers. 40 years and counting since their last good album
