Query: Their BEST DVD so far!!!

Hi, I've been an AC/DC fan since 1990. I've seen them almost 30 times only in this last Black Ice Tour. So I was waiting a lot this new release. Well... the concert is simply amazing. 32 HD cameras are working great together and the sound quality of this video is beyond belief. and the crowd? we'll simply the best crowd ever filmed on camera... have you ever seen an entire stadium jumpin' and rockin'?? Here you can!
