On the subject of Roy Z, Tribe of Gypsies is decent stuff if you're partial to some of that latin-style music mixed with rock. johnglen seems to have forgotten Judas Priest' Angel of Retribution too, which is one of my favourite albums to stick on to get through a bunch of work (if I'm in the mood for music while working).
As for Bruce albums, I'd probably say Accident of Birth is my fave too, though I do like Skunkworks a lot more these days. The weakest in my opinion is Tyranny of Souls, its one of the few albums with Bruce on that I feel has a lot of filler tracks. Not much of it really hits me like Tears of the Dragon, etc does.
As with generally all good music, some of the songs on each of the albums aren't done justice in studio form and sound far better live. When I think about it, not one song Bruce did live sounded worse than the studio version. I might go as far as saying I kind of wish someone like Kevin Shirley had produced all of Bruce's albums, I think they are mostly too "soft" sounding. After I watched the Bruce anthology DVD, it really gave a far better apprecation of almost all the songs.
At least none of it was as bad as The X Factor's production though.....forever ruined and therefore under-appreciated (when compared to the live sound of the same tracks with Blaze or even with Bruce).
