Anything recorded before an artist died, but subsequently released posthumusly (too late to spell that correctly, methinks) knocks me out.
A personal example is Dave Carter's last album Seven Is The Number. Released 4 years after he died and 6 after his previously last recorded album... It is eerie. Also listening to his older albums and realizing just how in touch with his own mortality he was... he's a remarkable songwriter who writes as well as Dylan, but in a bit of a more... esoteric and spiritual way. Also a bit more country (folksy country, not twang and incest country).
Unplugged in New York (Nirvana), Regretfully Yours (Superdrag), Abbey Road (Do I Need To?), This Is A Long Drive... (Modest Mouse), and Breakfast in America (Supertramp) are also great for zoning me out. And typically depressing the shit out of me... Same thing, right?
