I decided to have another download spree today, but this time, I decided to look at some old posts (from 2009-2010) in both "Albums You're Digging" and this thread.

Despite the terrible cover art, I still got this because I'm a sucker for lengthy post-rock albums.
Aphex Twin - Richard D. James Album
I'm surprised that I didn't get this album sooner due to all the praise that I've heard being given to it. I'm really looking forward to listening to this.
Pink Floyd - Obscured by Clouds
Even when I was 13, I still thought that this was an underrated album. I'm so glad that I have the chance to listen to this again.
Jaga Jazzist - A Livingroom Hush
I've been meaning to check these guys out for a while. I would have gotten
One Armed Bandit if I found a working link, but this will have to do as a starting point in their discography.
I got a lot more than these albums, but I'm really tired at the moment, so I don't feel like typing a list.
