I only own one Bon Scott vocaled album but I have heard quite a few songs. Back in Black was my first introduction to the band and, at that point I had no idea that they had just lost their singer.

Honestly, I never cared for Johnson's voice but I really like the sound of the band as a whole. I don't turn to rock and roll when I am looking to hear a pleasant voice anyway. But I can't think of anyone who would fit the band better without the re-animation of Bon.

I am going to get a couple of the older ones.

The Razors Edge and TNT are really pretty close actually but Ballbreaker seems to have more emphasis on the drum/bass and rhythm guitar.
