Tell Us about an Album That Took a Long Time to Grow on You


I'd love to hear about records you own that left you cold or disappointed when you first heard them but really grew on you with time. I'll give two examples.
The first is Paul Simon's collaboration with Brian Eno from 2006 entitled "Surprise." I really, really disliked it at first – so much of it felt to me like noise. But over time, I came to appreciate it.
The second is Donald Fagen's "Sunken Condos." I am such a huge fan of him and Steely Dan that I was shocked by how little affection I felt for that record when I first heard it. Now, the better part of two years later, there are songs on the album that I can't get enough of. Strange how this happens…
Your examples?

Rock music related;
as the 80's came into a close and the 1990's began, I was still into Hard Rock and Metal!  Well, a new genre was being hyped for the mainstream, it was coined, "Grunge". Nirvana, Soundgarden and a band called Pearl Jam lead the changing of the guard.

I caught onto both Nirvana & Soundgarden early on. Pearl Jam "Ten" however took a little longer to grasp. Another year would pass before I truly grasped this release.  As this music flooded the air waves and MTV, I caved into submission.  After 10 years since its release, we now know that, it is a masterpiece. Still holds up in 2016.
I just recently, yesterday actually, put on Ornette's-This is our Music. I am really surprised how much I enjoyed it. Especially considering how I felt about it over 7 years ago when I first picked it up. Id listen to it only very occasionally to see if anything changed. Until yesterday I was ambivalent. My system is better now, maybe I'm a better listener now I don't know. But, I'm gonna put it on again right now and see if side two speaks to me like side 1 did. 

As as a band the Grateful Dead were not something I took a shine to, initially, at all. What is the big F'n deal was my exact attitude. As it turns out they and the rest of the dead family offshoots of the band have been over the course of it a very cool part of my life musically and I have had the honor to have experienced some of the best most joyful experiences of my life at shows. All the while I might add never taking anything stronger than a cup of coffee, a few beers and/or a bit of weed. 
Jah Wobble/Evan Parker "Passage To Hades" -- extremely sophisticated mixture of jazz, avangard and Irish folk.
 
Yes - Big Generator.  Only liked Shoot High Aim Low when it first came out.  Thought the album was too blatantly commercial.  Almost 30 years later, now thinking this is a great album.  Songs are strong; arrangements and sound quality are great.  
fourwnds, I didn't initially care for Workingman's Dead--I came to like every tune on the LP. 

bdp24, I liked your Big Pink post.  I took to that album immediately.  I was familiar with some of the tunes from the radio but didn't know who did them and was pleasantly surprised to find them on the new LP I was spinning.  BTW, I once played a couple of tunes with Bobby Fuller's drummer.  He was a hometown buddy of our drummer, ex-Mother Jimmy Carl Black. I had actually forgotten about that experience until I read your post about the bassist, so thanks for that!
