“Flow is one of the hardest elements of songwriting to capture. It’s a combination of the fluid transition between song sections as well as a product of the interplay between rhythm and melody that creates a cascading feeling, and it often hides in the smallest details. I’d also argue it is one of the most important emergent properties of post-rock and post-metal, particularly the instrumental type. The illusion of being dragged along a river is among the genre’s most significant qualities. Ghosts of Glaciers is an instrumental post-metal band, set to release their third record of the decade, and their first since signing to Translation Loss. They are up against some stiff competition this year, including Russian Circles and Cult of Luna. Have they mastered the art of the flow, or is the river all dammed up with nowhere to go?” When the levee breaks.
