Most of the album was created and recorded here at Studio 880, in a part of Oakland called known as Jingletown. Studio 880 has played host to the likes of Chris Isaak and Iggy Pop, but it’s Green Day’s compound, with crates of their gear stored among the classic cars in the parking lot. Its high walls and barbed wire fencing keep the good stuff in, and the bad stuff (suffice to say, Jingletown is not the Bay Area’s nicest neighbourhood) out. Bassist Mike Dirnt reckons he was close to getting RSI, so many times did he walk through the doors here during the making of 21st Century Breakdown.
