The one Zeno mentioned is Minotaurus. Two issues published, as far as I know. The first one was more of an art zine w/ graphics/art/propaganda from Axis Sanguinarius (pre-Blood Axis, in other words), Big Body Parts, Big City Orchestra, Crash Worship, Haters, IOS, E. Lunde, Slave State, Z'ev + others. Issue #2 was more of a conventional zine, w/ reviews + interviews -- Coil, Zeni Geva, Cop Shoot Cop, Allerseelen, Blood Axis, Merzbow etc.
some more that I came to think of ~
- The Feverish, Germany, published by Willi Stasch/Cthulhu Rec.
- Lockjaw, UK, done by Robert Maycock (Satori). Mid-90's.
- Silencer (Katharos Foundation, Netherlands). Very TOPY, or should I say only about TOPY/PTV stuff.
- I.H.T.S.O. (International Hopeless Tunes Support Organisation, Germany 1988). One issue, one page on RJF, plus more obscure stuff.
- Phonetic System. UK, early 80's. I only have one issue -- We Be Echo, Nanavesh, Possession, Attrition etc.
- Gneurosis, UK, early 90's. Two issues (?), Organum, Konstruktivists, plus lots of post-situationst kind of stuff. Good one!
- Rigodon, Anima Mal Nata, Holland, 2004. Only have #2 -- Crank Sturgeon, Luasa Raelon etc
- Exoteric, Italy.
- Grim Humour/Adverse Effect, UK. Enough noisy stuff to be incuded?
- Impulse, UK. w/ comp tapes for most (all?) issues
- Tone Death. UK, 1980's.
Maybe these are not enough purely focused on music, but more so than some others already listed ~
- Eskhatos, US
- The Fifth Path, US
- Ohm Clock, US
- Esoterra, US
