Input: Consider Input: So they release a DVD to say how good "Back in Black" is (as if we needed to be remembered of that...) and they put a photo at the front cover with SIMON WRIGHT in the line-up, instead of Phil Rudd! Wright joined the band THREE YEARS after the recording of "Back in Black".This fact alone is a very good omen of the real intentions of this product: to make easy and fast money and offering nothing new about this classic rock album. Useless.
Output: Negative
