Please share freely and never sell. I upload all of this for free in my spare time, and no one should profit a penny from this material but Slowdive.
If you would like official versions of this material released, please contact Slowdive directly. I will immediately remove any content that has been officially released, or any other material Slowdive does not want me to upload.
