Post them, enlight us.
There are no good ones, no.
I toyed around with making an EAI chart awhile back but gave up when the salient nature of "essential" releases came into conflict with the esoteric nature of the genre itself and the "authenticity"-obsessed nature of the fandom.
In other words, it's pointless because anyone seriously interested will quickly find all of the major releases and move on their own from there via blogs and RYM, and those who don't care will relentlessly shitpost at posters whose top 50's are littered with these now-essentials.
It's also nonsensical to group the three together.
