The first one is scraping the good ol' contact mic over a block of concrete with wind blowing in a microphone at the other end of the room. With the amplifier being turned on, there is occasional feedback hums too. The second piece starts out with a voice moaning, along with more feedback hums and scratches. If you think that noise shouldn't per se be recorded by the best standards posisble, or that the impact of noise increases, if recording standard decreases, than this is your cup. If you don't wish to receive this, then let us know.
Any feedback is welcome .
Forward to your allies.
