Well, Definitely Dream Theater - Octavarium, as it must be something very profound, full, expressive, emotional and so on. (Don't judge me this is how I feel, not that other music does not have the same qualities, but for me they touch my soul) BUT I would not listen to it, I would play it (the lousy way I can) stepping one last time into that ocean of sound, becoming for the last time one with my guitar. As afterwards, I would like to have my ash spread from the top of a mountain, by my dearest friends to whom I will always be grateful that were always by my side when I needed help. At that moment I would choose to enjoy the sound of nature.
