I'm a bit amused that the discussion has led to so-called "noise tourists" being at fault, especially given all the examples Mikko listed are releases made in different countries to Finland and then seemingly exported to foreign lands where they feel lost and unwelcomed. Who do you think bought -and brought- those releases over here in the first place? You guessed it - tourists! So I personally find fault with that term, given tourists, explorers, expats or other outsiders are often the ones willing to spend considerably more money to travel to different lands, buy artifacts at inflated costs, redistribute them from a homeland to another place (or "loot" even, if you perhaps consider taking these cultural items from different lands as a form of colonialism), and relay the information to more enlightened types overseas who would appreciate it more than the savage locals. Maybe when you say "noise tourist", you mean "noise migrants" or "noise vagrants" instead?
Anyway, there is something to be said about Old (as in out-of-date, stale, expired, rotting etc) noise, in the sense that all products have not just a cultural lifespan, but a physical one. Either the audience dies, or the product does. It starts its lifespan as something purchased, handled, experienced and in rare instances, maybe even enjoyed repeatedly or celebrated from release day. Then it gets shelved, maybe revisited and savored in special times as a form of nostalgia or to put in context with successive releases. Finally though, if it gets lucky, it gets relegated to that preservative, polythened status as an "artefact" or "collectors item" worthy for museums, libraries or that sad wall on the record shop or retirement fund. A few REALLY lucky ones might even get that coveted "reissue" status for those savvy, self-righteous posters above me who will settle for a simulacrum of the original. But for the most part, all products get forgotten about, dented/damaged/scratched over time, falling out of fashion as technologies similarly falter and fail, swapping hands in ever-more desperate circumstances with ever-diminishing Discogs condition grades (and maybe even being seen/understood by later [de-]generations with euphemisms ranging from outdated to "culturally inappropriate" to Entartete)... until eventually they are landfilled or destroyed. Dementia Noise. It'll happen to us all eventually, it's just a matter of time.
