Album(s) That Took The Longest To Come Around To

A different post in this forum ('music') made me think of a couple:

right after I read the review in Stereophile of Steve Earle's '97 releases, Train A Coming and I Feel Alright, I went out and bought them.  It actually took me a while to start liking them, but after I did, I couldn't get enough of them.

Astral Weeks. Wait, I still don’t get it. 

Spirit-Twelve Dreams Of Dr. Sardonicus. Was familiar with this album since my early 20's/late 1980's. WRIF/Detroit had a DJ(Arthur Penhallow) that loved playing "Nature's Way" and I thought it was just another "Baby Boomer/Hippie" track without giving the album any thought. Proceed to 2010 when I started collecting vinyl and found a 2nd pressing(Epic/Orange) and realized the excellence of the complete album/recording. Easily a Top 100 Pop/Rock recording of the 1970's!
