What are the "Must have" LP's?


I have recently re-discovered the LP. I listen to Jazz, blues, classical, and some rock. I was curious as to what my fellow audiophiles here on audiogon believe to be the albums that you simply MUST HAVE. As a sub-question, What LP's do you use to show off your system? Since I am just getting started, I have no real opinions yet, but as I become more and more familiar I will post my findings. Thanks.

getz/gilberto speaker's corner - everyone needs a copy of this album and this kills the SACD I have.
miles cookin/relaxin/steamin/new/workin 45rpm analogue prod - take your pick, they are all classics, too bad a couple are oop already.
Chet Atkin's Progresive Picking, Yes's Fragile (UK Plum label), Richard Thompson's This Old Kit Bag, Leinsdorf's Romeo and Julliet on Sheffield.
Anything to do with Talking Heads. Solo projects as well as group efforts. The mix and sound are as good as vinyl gets.
Not only do I like a particular artist, I collect by label. In Jazz, Prestige, Savoy, Good Time Jazz, in Blues,
Excello, Flyright,Wolf,Acoustic Sounds, Blue Horizon, In Rock I generally like British pressings of Cream, The Who,
The Doors, The new Mofis with Allison Krauss & Union Station ios an absolute jem alokg with Eva Cassidy's Songbird.
