>>454138OPN covers are generally all great. Garden of Delete is probably the one that does the least for me on an its own, but conceptually it does fit with the whole "moody 80s millennial teenager who is into the occult but also computers" vibe.
The cover of the first HTDA release has always been one of my favourites in terms of things Trent Reznor was involved in, despite the project itself being extremely forgettable. It's got this "early 2010s artsy photoshop collage posted on tumblr" thing going on which perhaps dates it a bit, but i still enjoy it
