Blessthefall have posted their video for "40 Days…" The song is from their 2011 album, Awakening, and the band explained the zombie-themed concept:

After waiting around for several months for the new season of The Walking Dead to start back up we decided to take matters into our own hands and make our very own zombie flick, with a Blessthefall twist.. We dont take ourselves too seriously, so we added a proper dose of comedic value. The video was a blast to film and we even added a very special female guest zombie at the end.
