Everybody has a language or code that they use with their wife or their girlfriend or boyfriend or what have you. It's a language aside from the language they have with strangers. I've always been maybe an abuser of alliteration, but I've always loved it and I like how those words sound together.
'For Unlawful Carnal Knowledge' took a year to record; that's why the playing on it might sound somewhat labored. 'Balance,' on the other hand, was written and recorded in only four months, so the whole process was quicker and more immediate.
