for my new lp on nattmaran I tried to select locations with care... we used an abandoned factory hall, everything in concrete and incredibly high to the ceiling. incredible natural reverb / echo... also an empty oil cistern.... no editing needed afterwards. what I enjoy is when concrete / organic sound can get as violent as electronic but still keeping its untamed feeling.
I also have vague memories from an alfarmania show in umeå (2005) where we blew the sound system and instead improvised a set inside a cave. crawling under large sheets of metal, tape manipulations, minimal electronic equipment - more focus on concrete sounds... result was rather satisfying.
I think there is a lot to gain from using recording locations that makes the sounds live a life on their own... take it to their maximum potential.
norbergfestivalen in sweden is a good example of how these locations can be put to good use. in particular the "mimer" hall...
but for recommendations I have no idea...
