The Atlas Sound tracks posted on the Deerhunter blog in 2008 and 2009, by the end of which Bradford Cox was no longer using the site to present new music regularly. The online-only Atlas Sound oeuvre reached its peak early in 2008, especially with 'Children's Hospital'. Many of the links to the tracks are now broken, but I assume you can find them via Soul Seek or similar programs.
