I guess another way to say it is “what’s your grailz”, but I’m curious about what records are sought out by people and learning why it’s important to them.
For me, it’s the Aquarius/Chinook 7” by Boards of Canada. Huge BoC fan and it would be the last record I’d need to complete their official discography on vinyl. Also pretty sure this verison of Aquarius is different than other released versions. Every once in a while it’s up on Discogs for $$$, but if I saw it in person I’d pay whatever the sticker said.
Crowbar, “Broken glass” — apparently the record label withdrew all its releases, claiming it didn’t have publishing rights. So it’s not allowed for sale on Discogs per the “unofficial release” rule, and I don’t know that this record has been reissued on vinyl.
The other albums I’d put in this category are available, they’re just pricey, like Bohren & der Club of Gore, “Gore motel”. I keep tabs on Secret Chiefs 3 7" singles too, but they run pretty steep for one track per side…
