For the DTE camp, some of the best and most memorable recordings are those done in a raw, "amateur" fashion. ENT 1987 rehearsal, Doom live, from the split cassette with Battle Of Disarm, will always be above any of their studio recorded material.
The Instinct Of Survival "demos album" is pretty much in the same vein - 14 raw, unpolished songs that can not be replicated in a professional studio. Self-recorded by the band on a 4-track. 400 copies on 180 gram black vinyl, 24pt board jackets.
