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

To start?

Desert, island, mountain cave... If I'd stay with "modern" music, and as long as I could have my system, these would be three to start "The 100 Collection":

Pink Floyd: Meddle
Can: Soon Over Babaluma
Wether Report: Black Market

These threads are always a great source for music you haven't heard although i'd probably err on the side of streaming many before buying a vinyl version.  Also obvious is that few here can confine it to three but i'll do my best:

1. Allman Bros--Live at Fillmore East--many recommendations on this one

2. Santana- Abraxas--played this one frequently at my student apartment in France in 1974 and my landlady next door begged to know what it was--i went and bought it for her and then got to listen to it through the walls nearly every night for a year--she told me it saved her marriage 😀 

3. Little Feat--Waiting for Columbus--IMO best live album ever recorded

The Allman Brothers Band - Fillmore East

The Clash - London Calling

Led Zeppelin - Houses Of The Holy

Hellbound Train-Savoy Brown

Rock n Roll Music to the World-Ten Years After

Rides Again-James Gang

just to offer some new flavor. Many more already named. How can you not love these discussions?

These are the three I HAVE to have, due to their sonics and sheer musicality.

John Coltrane & Johnny Hartman

Supersax Plays Bird

Just For A Thrill (Weslia Whitfield - a little rare, hard to find, but worth it)
