Zero Day is the fourth studio album from nerdcore hip hop artist MC Frontalot. It was released on April 6, 2010.[1] The first single, "Your Friend Wil", is available for free from the official website.[2] The album's cover art was drawn by Jhonen Vasquez.
The album's last track ("Painstakingly Concealed Secret Track") is the key to a puzzle which leads to a hidden track. To congratulate the 56 fans who solved the puzzle before the album was officially released, a game ladder page was erected on the official website listing each fan's initials.[3]
