Well, I'll be fair: "generic" isn't really the right word. It's like the difference between Night Ranger and the 100 other bands of that time that had one hit ballad and otherwise didn't make it. Night Ranger were (and are) real players, and even if you don't like the music, you have to sort of respect their abilities. Some of the other one-hit wonders? Maybe not so much.
There's no doubt that AB are talented, quality players, and for my money, a song like "Cry of Achilles" is as good as it gets. But each style has it's tropes, right? And like Mikey said, I gravitate to that 70's riff-rock vibe, more than the 90's metal vibe (I always refer to that chugging, growling E-string rhythm, like the part right after the first "scream" and into the verses to the Sons of Apollo song "Coming Home" as the example of that).
What's this about a "solo record on the shelf"? I know he was working on material for a while and then went in a different direction with the lyrical focus, but did he actually record that early material?
Also, what about the Mayfield Four stuff? He played a song or two of their solo, but it was all in that stripped-back acoustic style, so I have no idea what it sounded like originally. Is it worth seeking out? Is it even possible to seek out?
