Panopticon is the post black metal project of Austin Lunn. Much like the title implies, Revisions of the Past is Lunn's way of righting things he did long before he had the knowledge and skills he has now. The album is a rework of two previous Panopticon albums, On The Subject of Mortality and Social Disservices, Lunn felt he didn't do justice to at the time of the original recordings due to lack of equipment and knowledge. Now, with the help of Spenser Morris and Colin Marston, Lunn and his listeners can now hear these albums the way he envisioned and intended for them to be heard.
