This is exactly what makes this track a bit "mystical" if I may say so.
I have one version on the '78 official Equinoxe vinyl LP albym, the same as I have on my two Equinoxe CD albums.
Resently I bought a 78 promo 12" single, s.c. Equinoxe 5 "special remix" version (same track on both sides) and surprised I am 'cos I can't hear any difference compared with the official '78 LP-album and my CD's. There is a different version though on the '84 Musik Aus Zeit Und Raum vinyl. Maybe it's the same "different" version as on the Images album...I don't have that one.
Could it be that the MAZUR LP have the real '78 master tape version or what is it?
Maybe it's just an individual thing to judge what the difference is?
Equinoxe -78 LP
Equinoxe CD's (maybe a slight difference because of the sound media)
Equinoxe 5 -78 'special remix' promo
JMJ Essential -83 LP
= same version
JMJ Musik Aus Zeit Und Raum -84 LP
just by my observation...
