R&P: What is THE album in this section that is perceived as the standard?

In other words, which albums do you HAVE to find some good in or
people will sh*t on you verbally and declare you a heathen?

In RHH, I think it 36 Chambers by Wu-Tang and Illmatic by Nas. XD But
there could be more. I don't go there as often as I would like because
of boring and unfunny trolls.

Maybe DSOTM or Revolver? :/
