You know I have an enormous respect for Passion And Warfare, one of the truly great instrumental rock guitar albums. I also rate Surfing With The Alien as a premier album in that category. It was a game-changing album, and IIRC, the biggest selling rock instrumental album since Jeff Beck's Blow By Blow. I think Satriani has released a number of first-rate instrumental albums over the years, but Surfing really was a major creative and artistic statement, and inventive in its own right. The album is loaded with tremendous songwriting, brilliant execution, creative and inventive playing, and superb melody. It was a commercial success, which also helped usher in an era of instrumental guitar rock albums. Without Surfing, who knows if Relativity green lights Passion And Wafare.
