I'm liking the Mexican Summer reissues, but I've read they are remastering the originals to include cleaner sound, more separation etc, partly because of poor transfers that occurred in the early days and paw tracks releases.
It's cool that ariel is so involved in the remasters, but I would be much more excited to hear uploads of the pristine originals like this one, just as Ariel originally made them - pre transfer, pre paw tracks, pre remaster.
PDM here - this is my transfer of "Nile Pan" original mixdown C90 and nothing was done to it besides setting azimuth at the middle of the tape and setting the speed where man deemed "correct" (appeared the deck it was recorded on was running very fast)
The earlier stuff (Underground and before) tends to be considerably higher fidelity than the classic HG recordings because it was done either direct, sound on sound or 4-track, and was less deliberately overloaded at mixdown
This is known to be Ariel's first multitrack recording and was done on a Marantz PMD 720 or 740
I would like to take this opportunity to state that great care has been taken NOT to artificially improve the sound on the remasters coming out, beyond the necessary EQ to get the albums to sit together - the original transfers were really that bad.
You're hearing the stereo separation, noise and distortion levels etc as it was originally mixed [except the few we've redone due to missing tapes] There still isn't (and probably never will be) a way to "enhance" stuff like this in a way that won't set your ears on fire from screechy digital artifacts - I have a high-school level understanding of information theory and love screwed-up recordings too much to let something like that happen, so don't worry
