Deerhunter frontman Bradford Cox originally released "Mona Lisa" as a free demo on his blog. Later, the prolific and sometimes controversial artist dug into his hard drive and brought in MGMT's Andrew VanWyngarden to rework the tune into a dream-pop gem for his solo project, Atlas Sound. "It's kind of like my bedroom, you know? It's just a mess. It's just all this shit everywhere,” Cox told Rolling Stone, about his body of work. "'Mona Lisa,' it's not even a song that means that much to me. I can't explain why. It fit in that part of the album."
