Far from being ‘a clear violation of the property rights of Ayn Rand’, the album Concerto of Deliverance is a tribute to her achievement and, among other aims, a way to draw new readers to her works (which it is already doing)..As to my using and benefiting from Rand's works: don't all objectivists? Is someone who makes a movie of Anthem (now in the public domain) being immoral? Is someone who names their children after characters in Rand's novels being immoral? Is calling a website or organization 'Objectivist' being immoral? Is applying objectivism in one's life and career, and making money from that, being immoral? If it is, then we should all refrain from deriving any benefit from her, put her works in a vault, and make them taboo.
Personally, I have no problem with taking the concerto as a springboard for an original work (I've done so myself, with my own "Bolero of Deliverance.") I think the real reason for offense is that the Concerto of Deliverance, as a fictional piece of music, is so idealized that it's like looking for Atlantis; if it were to ever be discovered, it probably wouldn't live up to the hype, and no one wants their illusions shattered. That is why I personally fear an Atlas Shrugged movie: because the soundtrack will never live up to the expectation of that "lost" concerto.
