I'm probably stating the obvious here, but I'm talkin' about:
John Coltrane - A Love Supreme (Impulse - 2003 reissue)
What a great album! Even though I'm a big fan of jazz, I somehow never got to getting this beauty. Now I have and it's as good as everyone says imo (I heard it once a while ago, but 'really' heard it good since I received it today).
It's also another fine example of a great reissue, package and sound-wise, for which they tracked down a 1965 master tape, instead of the 1971 one used for all previous digital incarnations of this album, which contained some unwanted processing.
"This tape preserves the sonic details with vivid accuracy: Elvin's cymbals, the deep intensity of the vocal chant and the openness of the group sound" - Rudy Van Gelder.
