Recording of December 2019: Abbey Road (3-LP Anniversary Edition)
Here are seven things you need to know about the three-LP, newly remixed—by Giles Martin and Sam Okell—and remastered version of Abbey Road, all of said re-ing done in honor of the album's 50th anniversary:
1) According to Universal, the remix was done from the original eight-track master tape, not from digital files made from that tape; inscriptions on the lead-out areas of all six sides suggest that these new LPs are the product of half-speed mastering. All surfaces on my review copy were noiseless.
2) Listening to these new mixes, the dominant impression is one of increased articulation. The equalization isn't drastically different from that of the original mix.
