Most Records in that Nineties period were pressed in the thousands- and big DIY hardcore records from the time would easily sell 10,000-20,000 + copies. Even in the early 00's Records would be pressed multiple times, something that seems to rarely happen now as records transition- for most people outside of collectors and older fans- to an adjunct collectible representation of a download , and are seemingly pressed around a break even point of 500 copies. THe micro-pressings of 300 to me seem like the most insane thing, where there's not even an outreach to try to reach a broader audience - which does require a bit of effort- so it's basically like the Records don't even exist. Same time, the broad availability of downloads, youtube and other sources completely alters the equation. I've never been able to fathom the idea of making your music hard to get / ultra-limited as a promotional means, as it seems counterintuitive to the entire spirit of hardcore, which was to spread ideas, infect people's minds with them and take over.
However, one thing that completely fueled the surging wave of 00's hardcore - particularly interest the stripped down 80's hardcore, European Thrash and Japanese harcore was the music finally became broadly distributed beyond having to write some one overseas with a tape or record trade and wait a month or two to hear it or dig through record bins for a few years to finally find a copy. Finally all this Great music was available for people instantly. It does poses a broader question of fatigue of having such a cultural overload of music that will ALWAYS be available, piled on 30 years of punk history of a genre, with an easy template to continually produce more. Anyway, Pot of coffee's almost gone and Better get on it.
