Cult Of Luna & Julie Christmas made a massive impact on the metal world with their debut collaborative album Mariner in 2016 and subsequently did some pretty extensive and exclusive touring. Now the collaboration has announced an extended documentary about their touring and is currently streaming an abbreviated version above that runs about 16 minutes long.
There's also a live album coming that was recorded in De Kreun, Belgium in November of 2016. Both the extended documentary and live album are due out in April 2018. If you haven't gotten Mariner yet either, you're missing out big time.
