The following is from the Double Core MySpace page:
Double Core is part of the ongoing Pink Floyd tribute project at www.neptunepinkfloyd.co.uk. Originally an internet hoax started by some anonymous Pink Floyd fan, the artwork for this non-existent album ended up being posted to the forum at NPF. Since many of the users at NPF were involved in recording covers of Pink Floyd songs as a tribute, it made sense to see what would happen if everyone flexed their Pink Floyd influence and brought this hoax to life. The entire album can be downloaded at the following site: www.the-clock.co.uk/NPFDC/ It's presented in various formats, allowing people to download whichever format they prefer. Here's the artwork .. DoubleCoreArt You can use Foobar2000 to convert the files to wav and burn them onto a disc. This project was spawned at neptunepinkfloyd.co.uk and more information is available at the forum there.
