I am not sure if you understand the connection between a person and their eventual output of music. It doesn't happen by a simple click of the finger. Even not with Adrian Smith.
DVDs that contain interviews with Adrian Smith or other members, can you enjoy watching these if you'd have a little voice inside the back of your head, saying "yeah right" after every sentence?
Talk about music, is often no hollow talk. As much as it is connected with personality, it is undoubtedly connected with artistic values, in other words: with integrity. Passion, motivation, these are the catalysts that lead to output, the music. All comes from within and it can be uttered by musicians. If you take everything that is said with a grain of salt, then I don't only wonder if you lack the appreciation of but also if you have an idea of how creating works. You can say you're not interested, but denying it is an entirely different matter.
However, if you say you are interested in what you hear music related, that might mean that you are interested in talk about music. In that case, you do believe in artistic values, because they are the core of about everything a musician does and says, definitely if it's music related.
