In 2011, Chambers worked on new material with English singer-songwriters Katy B and Charlene Soraia. He also teamed up with Example, co-writing the song "Microphone" which featured on Example's album, "Playing in the Shadows". In the same year, Chambers worked with Marlon Roudette, producing and co-writing her single "New Age". A track Chambers had written with Julian Lennon titled "Never Let You Go" was released on Lennon's album "Everything Changes". Chambers collaborated with BBC2 for two three-part programmes: "Goldie's Band: By Royal Appointment" airing in April and "Secrets of a Pop Song" which aired throughout July. Through the series, Chambers worked alongside Mark Ronson to create a single, singer-songwriter Rufus Wainwright to create a ballad, and British band Noisettes to compose an anthem. Chambers & Rufus' "World War III" features on the digital version of Rufus' album "Out of the Game".
