Panopticon’s “…on the Subject of Mortality” is a poignant exploration of grief, written in the aftermath of the loss of one of Austin Lunn’s parents. Originally released in 2009 and remixed in 2016, it delves into the emotional depths of human existence, processing death, and the fleeting nature of life. With atmospheric black metal and post-rock influences, the album reflects Lunn’s personal journey through loss, deeply inspired by the existential themes of The Seventh Seal.
