The project first came to light eight years ago when Heafy was looking to explore his love of black metal, with Emperor’s Ihsahn hooking up with Heafy to make an album.
Updating fans on the record's progress, Ihsahn says on Instagram: “It’s Mrityu Monday and me and Matt Heafy have been tracking some killer vocals.
“The current situation prevents us from travelling, but with this technology, it is almost like we’re in the same studio. Matt is absolutely killing it and we’re making great progress every session.”
Heafy later shared Ihsahn’s post on his own channel.
In an editorial piece on Metal And Honey back in November 2012, Heafy explained why he loved the genre so much, saying: “Black Metal for me has always evoked feelings of something beyond the realms of normality.
“When listening, one is usually taken back visually to more savage viking or medieval-eras – it's not unlike being immersed into legendary tales set within the landscape of the cold wilderness of the Northern-most, snow-engulfed foreign and forgotten lands.
“The note choices and performance aspects always pushed the boundaries of what basically anything else in any genre of metal were doing.”
Further details will be revealed in due course.
