Re: Passion and warfare or Flying in a blue dream?
Man, I can't really see this one.
"Passion and Warfare" was Vai's breakthrough album - "Surfing with the Alien" would be the better comparison.
Meanwhile, "Flying in a Blue Dream" was Satch's "commercial" album, where he'd done well enough on his first that his label encouraged him to start adding vocal material with his instrumentals. "Sex and Religion" is probably the better comparison, or possibly "Fire Garden."
The problem here is while both albums are impressive, I don't really love either. For Vai, really his "Alien Love Secrets" is the only album I still listen to these days, and for Satriani, either "The Extremist" or more likely "Crystal Planet" would be the one I'd choose if I had to choose just one.
But, comparing Vai's most important album to Satch's second or third most important album is sort of odd, you know?
