Jonny Greenwood: We love recording there because we’re allowed to chew gum inside the booth. Radiohead is a big gum band. We love gum.

Thom Yorke: Gum is the impossible meal. It’s illegal to swallow, so you have to always be chewing it. A fabulous crime is that I actually swallow my gum all the time...

Nigel Godrich (producer): I had previously worked with Radiohead on The Bends, as well as on Thom’s solo albums Songs About Gum and More Songs About The Indestructible Meat Known As Gum, so I was very excited when they asked me to help them produce the new record.
