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.
