The follow-up to Duffy's 6.5 million-selling Rockferry album is out this November, and her record company believe it marks a significant step forward in her songwriting.
Endlessly will be released on 29 November, preceded by a single, Well, Well, Well, which features hip-hop band The Roots.
Speaking to music industry magazine Music Week, Duffy's A&R man Simon Gavin said: "She wanted to move on to other areas and try something different, to come back with a fresher approach. She didn't want to make the same album twice."
Rockferry was co-written and co-produced by former Suede guitarist Bernard Butler with involvement from 60ft Dolls' Richard Parfitt. It had a noticeable Sixties sound that Endlessly is moving away from. Duffy has lately been working with veteran singer-songwriter Albert Hammond, the father of Albert Hammond Jr of The Strokes.
A&M Records' managing director Orla Lee believes that Endlessly will solidify the north Wales singer's reputation. "We see her as a classic artist that has a career around the world and she has delivered an album that feels like it can sustain that," she said. "It will be a fresh new album at the end of the year."
