The demise of techno has very little to do with mp3. Your blaming a medium for the death of a genre? Vinyl was around long before techno ever was. And looking back onyl ended up containing vinyl because HOUSE djs started using it. Now house DJs dont use it much anymore (none of the house DJs i know buy vinyl anymore AT ALL - but there are obviously some who do still, in my experience anyway)
Again this assumes that medium defines the quality of personal production. It doesnt, it just means like you said, that people put up shit tracks on their myspazz player, which is interesting from the perspective of listening to how people percieve a genre of music or where the 'Proles' of music making are heading as a semi-homogenous group - but it doesnt mean they are all making records to be put up on mp3 sites.100 times more shit music than in the heady days of vinyl
There are a lot of shit tracks out there, no quality control. But thats go F ALL to do with the makers, people will make music no matter what, thats life, nothing changed within people who have a dream of making it big, they were just given the opporunity to torture the rest of us with it. The propblem lies with....
The Aggregators (Distros NEW name.. lol ) They play the numbers game. Sure, put yourself out there mate, we'll take you on if you make a few sales its all good. Now this has massive down sides to it as we covered already - but it refused to see it all as a negative.
As for people selling vinyl from their own personal sites, cracking, i couldnt agree more, its something I want to do as well and im glad the distros have their fingers out of that pie it might mean vinyl actually makes money for people who need it. But then the process becomes nothing more than specialist vinyl sellers in bits and bats here and there.
IMO of course planky ;)
