I've heard that Leatherstrip's Solitary Confinement did unheard of unit sales around the time of its release, as did some of the early to mid 90's Front Line Assembly releases(along with a number of other major and smaller indie label acts)
Now...if a band sells 5000 physical cds, it's a celebrated event(and, well deservedly so)
I remember this magical sense of awe and enthusiasm in the American "goth industrial" scene in the early to mid 1990's before everyone was online...be it clubs, shows, etc.
You'd see someone at the store with a puppy shirt, and you became instant friends("holy crap, you're into them too???") Hell, it didn't even have to be someone into 242, FLA, Bigod 20, X Marks, or SA42...someone could wear a KMFDM or Ministry shirt and you'd feel compelled to make an instant bond.
I remember the excitement of getting Industrial Nation around 94-95, along with actual cassette mix tapes from people, Cleopatra catalogs, etc. I remember the beats seemed more complex, rather than the disco stuff today. (Don't get me wrong, I'm a HUGE modern EBM fan)
I remember word of mouth alone would bring a ton of people to even unknown industrial show lineups, whereby simply the fact industrial(as it was known in the US before "EBM" got recoined in the late 1990's for the scene) was advertised would bring throngs of the "goth industrial" crowd in.
Now days? A promoter can blanket everywhere with flyers, post endlessly on myspace/facebook/livejournal, and have everyone they know show up for a major scene band and maybe only get 50 people at best. (I remember seeing Icon of Coil in 2004 as well as Assemblage 23 and there was barely 60 people at each)
Clubs seem to be even worse; people would travel far and wide to go to a scene club; but depending what geographic region one is in...the advent of a packed club is a rarity. Much less so, are people who keep up with the music.
A vast majority of people who go to scene clubs/shows in the states seem to mostly be there to be seen and futher along their cliquey drama soap opera with their inner circles.
I was a bit late to the scene myself, having heard stories of amazing 242 shows from 1988, and even more amazing Puppy shows from 90' and 92' respectively...but aside from
the Los Angeles scene which always seems to remain rather sizeable; from the rest of America the "scene" seems pretty much on life support(as much as one would think it'd be booming what with filesharing and networking sites)
