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...
