Pedantic maybe, but still wrong.
The mix is called the Misterons mix as stated in the press release here on
dirty.org
"This release will be followed on July 10th with a retrospective look at the first 3 Riverrun releases – dubbed the Misterons Mix – which will be free to download to all who have bought the first 3 Riverrun releases. At around 30 minutes, the Misterons Mix will include a digital gallery of photographs and CD artwork."
