Building a 100 album vinyl collection 3 must have albums are?

Blood on the tracks-Dylan,Honky Chateau-Elton,Frampton - Comes Alive

I own many of the LPs suggested and agree they are great records.  However, my criteria for 3 must have LPs would need to take into account how they actually sound of a good system.  Many of the LPs I grew up loving, get very little play today as they just weren't recorded very well to start with.  So classic LP's that also sound great:

Junior Wells - Come On In This House

Joshua Redman - Elastic (/Brain Blade's drumming is fantastic throughout)

Jimmy Smith - Dot Com Blues

Oh, yes… those too.

Idris  Muhammad  "Power of Soul"

Climax Blues Band " Shine On"

Steppenwolf "7"

@norton Don't hear a lot about Climax Blues Band.  Always liked them.  Recently picked up a nice box set (Amazon) containing their first 5 recordings.  Put out by the Esoteric Recordings label.  Going back to 1969 for the first two records, it's very impressive the use of soundstage.  Some great engineering.
