Dude, people who've read the books are going to grasp the NIN reference, no need to explain it all.
But yeah, pretty much anything off NIN's "The Fragile" for me. Not even so much lyrically, but just the sonic vibe of the whole thing, sort of definitive of that 90s alt-rock feel. Amazing album too, easily Trent's most complex and layered. Heaviness, gentle piano melodies, crazy inventive synth stuff, it's just awesome.
Ah, Volbeat are awesome Redtail.
Actually met 'em a while back at a dual Volbeat/Iced Earth show, really cool guys.
Other music I'm pretty sure I've thrown out there in old other threads, Bad Religion's "Come Join Us" is pretty much
the perfect The Sharing song.
It's just about cults and lock-step mentalities in general, but man it's so lyrically on-point. Great melody too.

Not so much directly addressing the same themes as the books, like the Bad Religion song, but musically it's probably for me the most "nostalgic" of albums in terms of perfectly capturing that pretty specific "sound" of rock bands from the mid-late 90s period the books were being published. Likely it's the album they're supposed to be playing from in the concert scene with Jake/Marco where they're referenced, too.

Stupid this-decade-and-the-last-one with its stupidness, heh.
