Glad to hear that it sounds like something more real. I'll need to give that album another listen - was just listening to it today on my iPod, home from work but that's just not the same. It's one of my favorite albums.
When I first got into jazz, I was told that Kind of Blue may be the best jazz album ever. It is good, indeed, but not well recorded. The hiss of the recording is more prominent on my M80s than ever. I believe there were some recording speed problems as well. But the music is very good. I've heard others that I prefer, such as Benny Carter's Further Definitions, Ben Webster's At the Fair, Gerry Mulligan's Night Lights, and his album with Paul Desmond, Two of a Mind, as well as Brubeck's Take Five.
