I can't seem to find their original post on Facebook, but their Mediafire links were taken down. The compilation's very much a mixed bag, but here it is anyway. Has the 2.1 update, and all the tracks have been re-tagged to match Bandcamp standards.
Here's the note about the compilation from their Facebook page.
Spoiler
Starting right now until December 21, 2011, if you are in a band (Djent bands only) and have enough spare time to come up with anything, use that spare time to create a cover for a classic Christmas carol and send it our way. I will be creating a compilation like DJENT GOES POP but time it will be called DJENT GOES XMAS. Email me at [email protected] to send us your cover.
Just one more thing before you send your cover, comment on this note telling me what Christmas carol you will be covering so that way you have it locked in. The only Christmas carol I do not want any of you doing is "Silent Night" because I'm going to try to convince TesseracT to do it.
