Postdata is the solo project of Paul Murphy of Wintersleep. Info from his website: These are my grandparents. They passed away two years ago and left me thirty or forty pieces of songs in a series of dreams, not Coleridge-esque opium dreams though unfortunately, just regular dreams. Kinda sad dreams. This is for them. This is their daughter, my mother. I call her mom though, not mother. This is for her.
