Momentum is Jamie Cullum's sixth studio album, his first through Island Records. Jamie approached this record in a completely different way to his previous LPs, for the first time using DIY home demos as a blueprint for the majority of it's tracks... and for a while, using everything from iPhone apps, charity shop keyboards and cassette recorders as his "go-to" instruments during the process. The album was produced in part by Jim Abbiss (Artic Monkeys, Adele) and Dan the Automator (Kasabian, DJ Shadow) and the tracks "Sad, Sad World", which began life on a train journey into London and "You're Not the Only One", a song written in response to being a judge on Sky One's reality show Must Be the Music alongside Dizzee Rascal as well as the first single "Everything You Didn't Do".
