The new sound of 'live'

What the fuck is going down with these new Madonna clips, taken from her upcoming Sticky & Sweet Tour DVD?

The clips claim to be recorded at the River Plate Stadium in Buenos Aires, and yes, I'm sure the images were filmed there... The audio however, is a very different story...

I've seen the Sticky & Sweet Tour 4 times last year, and this is absolutely not how it sounded. In fact, Madonna was even more off-key than she was in her previous tours. However, judging from the new clips, she's supposed to sound almost album-quality?

Give me a break, this is a total fraud!
