The fact that metal music is no longer found exclusively in physical media removes much of that precious aura that can accompany physical art objects. Demo tapes were exciting and mysterious objects because one had to work to track them down. In the 1990s, I remember hearing rumours that there was a Pakistani metal band who had released a demo, something that seemed impossibly obscure and exotic at the time. I tried and failed to track down their tape, but I did track down others from faraway metal lands like the Phillipines and Peru and there was always a delightful frisson when tapes from distant lands finally arrived in the mail. Today, there isnt much frisson to googling something and finding it. Stripped of the aura, rare and obscure metal recordings become much more mundane.
