Query: Really weak

Brian Johnson's voice was practically gone by that time. Also, the production is simply horrible here.The songwriting is good, however, and would make for a good listen, except for the problems mentioned above.The fact is that AC/DC virtually died when Bon died. The guy was simply irreplaceable. He was the missing link that finally launched the Young brothers to stardom. Due to sheer talent, their momentum was so good, the inspiration at a peak, that BACK IN BLACK would have been a success with any singer, be it Brian Johnson or another. That they managed to record album after album after Bon's death, itás a tribute to their quality.
