Background
"Bunker" is an instrumental demo recorded during the Minutes To Midnight sessions and released on the LP Underground 12 CD. On the booklet, Brad Delson wrote: "We worked in so many different studios during the Minutes To Midnight writing and recording sessions. Our work culminated at Rick's house in Laurel Canyon. However, much of the material on the album actually came straight from demos recorded during pre-production writing sessions."
