Dormant Heart is the title of the fourth studio album by UK-based modern thrashers, Sylosis. The band have confirmed a January 12th release date for the album, via Nuclear Blast.

Despite the title, it’s not a peaceful album: It’s about a powerful force unleashing anger against everyday injustice and a sleeping society that lets these things wash over them.

Today we have the first taster from the forthcoming release - watch the official video for new track "Mercy" below.

Commenting on the track, frontman Josh Middleton states: ""Mercy" is the first single off the new album. It's got a pretty dark and heavy vibe to it but it's one of the most melodic tracks on the album at the same time. It's got a big slow, doomy outro with an octave pedal on the guitars so that's going to rumble some guts live. For this video, we wanted to keep it dark and claustrophobic. It's got some of the artwork from the album and inlay illustrated as well which came together really well."
