I hate to be a jerk, but if you got those files up on Bit Torrent and talked them up on the forums, you could get 1,000 or more people to download them.
I understand what you're getting at, but the added benefit of being able to physically communicate (and maybe even collaborate) with local individuals greatly outweighs the convenience of blanketing the internet in a manner not unlike pop-up ads. Online activism has its pros, but they only go so far toward positive action and actual results.
Moreover, like it or not, the effort to go so far as to deliver something tangible, include a message that espouses what is timeless, and provide contact information for further discussion is very impressive with regards to this brand of message-spreading.
I realize that the outlook and temperament of locals varies from place to place, but I get the feeling that thoughtful folks in most regions will be moved by such an effort even if they don't ultimately choose to get on board and contribute to it further. That isn't to suggest that throwing plastic at the masses is something that we should lean toward, but rather to assume that this music has the very real potential to foster valuable bonds when the corporeal medium happens to contain the genius of metal, a written account that elucidates that genius, and the gesture of having compiled such a package with the intent to pass it on in an optimistic manner (as opposed to a blind one).
I’d really like to hear what people here have to say about what they have found to be the most effective method of spreading this message in this particular capacity, as doing so could save some time and effort: in short, what has worked and what has not?
