As SB points out in his review, this is a great heavy metal show but with poor sound. I agree with SB that it is a stereo recording pretending to sound like 5.1, which by the way it doesn't. I assume that the blu-ray has the same or similar sound as the dvd, and all I can say is that it sucks. I have better sounding CDs than the audio on this disc, which really detracts from my enjoyment of this concert. Now if you like this flavour of metal, and let's face it who doesn't, the new AC/DC disc filmed in Buenos Aires is not only visually stunning, but sounds pretty close to being there.
