GREEN DAY said they are suffering "post partum depression" after the release of their
new album.
Frontman Billie Joe Armstrong says the band is so attached to '21st Century Breakdown', they had trouble releasing it.
Speaking to The Sunday Times newspaper, he said: "It's kind of like having post-partum depression. I finally left the album about two weeks ago.
"It has literally driven me crazy, but there is definitely a side of me that loves the chaos.
"You can end up out-thinking yourself, second-guessing, triple-guessing. You can chase your tail making a freaking record, especially with all the time we took off in the past three years, being at home and all that.
"Home can make you feel a lot more humble than being on the road. You know, 'Hang on, I had this dream of being a rock star!' Well, I may have made this grandiose record, but I've got to take out the recycling, too."
