i've now heard the mono AHDN, SP and AR- honestly, though obviously better sounding than what i've been listening to for 40 years, i'm much less impressed w/ the improvements of these monos than the revelation which is AR- i've always thought this was the best sounding B's album (w/ the best musicianship), but now it's so beautifully rounded, full of boldness and subtlety. mccartney's bass, which always ruled here, is now much more up front and dynamic- i read recently that one feels like they're right there in the studio- watching and listening to paul sitting on a stool w/ his fender laying down his bass lines, and this is absolutely true. even on lennon's and harrison's personal creations, paul drives them along. highlights for me were come together- forceful and punchy- the best B's opener made better, and i want you- now a true powerhouse of layered sound. what inspired lennon to play the most tasteful, jazzy, lead guitar (this side of 'something') in the band's history? but i think most of the talk will be about the side 2 medley, which perhaps benefits most from the remastering. the detail here from incomparable harmonizing, to night sounds, to straightforward rock will astound. despite lennon's cynicism, let's just tip our hat here and now to mccartney and martin for perhaps the best produced sequence in popular music. take notice- it's better than you ever imagined.
