[3] Aimée Duffy, her debut extended play (EP), was released in 2004 by Welsh music label Recordiau Awen Records,[4][5] following her success on the Welsh talent show WawFfactor in 2003.

[6][7] Following this release, a performance of Richard J. Parfitt's "Oh Boy" brought her to the attention of Duffy's former manager, Jeanette Lee of Rough Trade Records.

[12] Her follow-up singles, "Warwick Avenue" and "Stepping Stone", did not replicate her early success, although they still sold well; for example "Warwick Avenue" charted at number 3 on the UK Singles Chart.

[16] Duffy released her second album, titled Endlessly on 29 November 2010, which to date has charted in most major markets.

[17] Duffy also contributed to the films soundtracks of The Boat That Rocked, Patagonia and Legend.
