Buying my 1st new LP in 42 years..Suggestions?


I inherited around 300 pieces of well kept LP's from a friend in his 80's.. including a number of Sheffield and Direct to Disk Albums. So I purchased a Music Hall MMF 2.2 to play them. I would like to buy a new piece of Vinyl to get an idea how much has changed. Any suggestions of a well recorded LP to be my 1st purchase. I'm open to suggestions...

Trepaneringsritualen “Kingdom of Death”
but im sure it’s been suggested many times already.
I bought two re-issues of past great albums:  King Crimson - "In the Court of The Crimson King" and Elton John - "Yellow Brick Road".  Both 180 gram weight vinyl records.
What type of music do you listen to? I have so many to suggest and they are all audiophile quality.
If you like Steely Dan try Donald Fagen “Nightfly” on 180 g vinyl. It truly is an audio file re-release

180g Vinyl is heavier than “regular” records. 2x ?  Not sure. 

“ whatever you want” is not really a helpful response.  Nor is “buy 2”.

The OP asked WHAT to buy. 

What car should I buy? Whatever you want as long as you buy 2.

You got 300 LPs including a stack of Sheffields and direct-to-discs and the first thing you want to do is buy another record??? First thing I'd be doing is picking through that stack! Second thing, buying a good ultrasonic record cleaner. Third, zero-stat. Fourth, Stylast or other good stylus cleaner. 

The only way my first move would be to buy a new LP is if the Reference Recording 45 rpm 2-LP set of Doug MacLeod Exactly Like This is not in your stash. If that is the case then please whatever you do drop everything and track it down. Music Direct, Acoustic Sounds and all the usual suspects are already back-ordered, with no telling when they will press more. You might find one on Discogs.com but whatever you do just make sure you find one. If you haven't heard it go look for Serious Doin Woman on YouTube.

See what I mean??
Thanks for your responses! I am investigating them on iTunes.
In response to whart...
Rock, Blues, Jazz, Big Band, Blue Grass, Baroque.
Steely Dan, Dana Krall, Norah Jones, Stanley Turrentine, James Taylor, Doobie Brothers, OZMountain, KebMO, David Sanborn, Christopher Cross, Darius Rucker, and Jimmy Buffett. I really enjoy listening to good recordings.. I enjoy hearing the sustain pedal on Diana Krall, fingers sliding over frets, etc... I remember listening to a quality Chet Baker CD that I thought was good.  Doug Macleod and Tuba Skinny are two recent discoveries. I don't like the Tuba Skinny recordings but love the music and Erika Lewis is fantastic.
I see 180g.. I don't know what that is... Are new Sheffield recordings still available?

If stereo, Leonard Cohen Ten New Songs or, as mentioned before, Live in London will be a little different but great.

If you have an opportunity for mono, The Beatles 2014 mono remasters. Take a pick, for me Please Please Me is the one but all are great. Even if you are not a Beatles fan and never listen to them, it is worth it (happened to me, I bought all of them eventually).

If you are only looking to hear how much has changed, take The Rolling Stones Exile On Main St. Half-Speed remaster from, I think, 2016. It is still mud, but mud that you can see through now.
The remastered Beatles Anniversary Edition of Sgt Pepper’s Lonely Hearts Club Band album is truly awesome. 
Dead Can Dance - Spiritchaser  or Anastasis  on 4AD either is very well recorded. 
Anything on the Water Lily label. A Meeting By The River (with Ry Cooder) is fantastic, both sonically and musically.
Don't do it, you might be opening the flood gates to boxes of LPs all over your house and having your family and friends think you've turned into a hoarder!  Oh wait, that's me...

If you like Roger Waters, pick up Amused to Death from Analogue Productions.  
Fear - by John Cale! Paris 1919. Two long-time favorites by a founder of the Velvet Underground!
