Duffy is preparing to return to live performance for the first time in 15 years with a small concert in London on July 5.
In a social media announcement, the Welsh singer said the show will be a secret event with free tickets available through a limited ballot. The performance is expected to include new music, giving fans one of their first chances to hear what she has been working on after a long break from the public eye.
Duffy became an international name with her debut album, Rockferry, and the hit single Mercy. The album won the Grammy Award for best pop vocal album and made her one of the most recognizable voices of the late 2000s.
Her time away from music followed a difficult personal period that she later addressed publicly. Since then, she has kept a low profile, making this planned concert a notable step back into the spotlight.
The London show is expected to be intimate, limited, and focused on reconnecting with listeners.
