I really really liked that first Invasion album. The second wasn't as good as the first, but still enjoyed it. There wasn't much on the debut that I didn't like.
Vinnie is a really hard guy to figure out. The guy had an assload of talent as a guitarist and just didn't seem to understand how the music business worked, or maybe was just so full of himself, that it made him nearly impossible to work with (something I've seen/read/heard a number of people say about him over the years). I was actually watching a Vinnie guitar tutorial video just the other day and it's amazing how much guitar talent this guy had. He wasn't just some shredder-type player that we saw so much of in the 80's. He had a very unique playing style as well as an almost odd picking style. He took pieces of rock and country and put them together in his playing, although you wouldn't know there was any country influence in the sound, seeing him actually pick, it's obvious as hell.
