Some of my absolute favorites of all times noise/pe/industrial covers:
Grey Wolves - Punishment LP. Not just the front cover, but complete "crass style" 6xLP size poster sleeve.
Grey Wolves - catholic priests fuck children. Not just the front cover, but complete "crass style" 3xLP size poster sleeve.
Genocide Organ - mind control. Not just the image itself, but the also technical side - printed metal plate attached to black sleeve.
Typography works far more better than in many releases.
Organum - Vacant Lights LP, and of course back cover counted in. Artwork is simple but tasty. It is at the same time little bit "modern" (in 80's?), but at the same time also classic art in a way that there is proper skills involved.
and of course could go on for long time. I think these cases just show me that the "collage", the black & white "underground methods", all work very well, when it's done well. Each of the bands has done also pretty horrid covers later on. Like Organum with their dullest ever color fonts on white sleeve for last 10 years now...
BUT, I would strongly suggest, that perhaps there could be some braincell issues occasionally, but most of all, the aesthetic that you have been influenced just like you've been captured by the sounds. I wouldn't be surprised if Heretogo doesn't get much out of the artworks I posted, but at the same time, I don't see what exactly is the "special" in Neuhaus cover. I do like the "vintage" psychedelic circles, but image itself and the typography doesn't do anything for me.
It's like in the so called academic releases most often. Classical music releases have some of the worst artwork. And while I'd like it to be cover that actually could capture the mood of album... no no. Lets put some most tasteless abstract computer color fade to the cover that indeed looks like something sold at supermarkets in 2€ bin (see jewelbox reference). It is the context where one has come across something in situation which has been everything else but motivating. Indeed, jewelbox reminds of "regular". But in times, when special has become such a forced "novelty", I actually prefer regular. Like said. Over embossed digipak with nice golden foil lettering and little spot varnish and otherwise "stylish" grey on black art. Oh please, give me just something like Sutcliffe Jugend "s/t" CD and I'm happy! Cover with absolutely nothing. Technically or on design.
Therefore, the most I would value the very very basic idea on cover: Image(s) and it's purpose. LP would work great if it's just good image and necessary amount of text. So what is the good image? I guess different things appeal to different people. When I look some of my own choices, like Silence of Vacuum tapes for example, despite taking like 10 minutes time to make, I feel they are among the very best selections. Same tape, same design, with image of some skank on pvc miniskirt exposing some flesh from late 90's UK fetish mag.. would have been atrocious.
