25 is the third studio album by English singer-songwriter Adele, released on 20 November 2015 by XL Recordings and Columbia Records. Issued nearly five years after her previous album, the internationally successful 21, the album is titled as a reflection of her life and frame of mind at 25 years old and is termed a "make-up record". Its lyrical content features themes of Adele "yearning for her old self, her nostalgia", and "melancholia about the passage of time" according to an interview with the singer by Rolling Stone, as well as themes of motherhood and regret. In contrast to Adele's previous works, the production of 25 incorporated the use of electronic elements and creative rhythmic patterns, with elements of 1980s R&B and organs. Like 21, Adele worked with producer and songwriter Paul Epworth and Ryan Tedder, along with new collaborations with Max Martin and Shellback, Greg Kurstin, Danger Mouse, the Smeezingtons, Samuel Dixon, and Tobias Jesso Jr.
Upon its release, 25 received generally positive reviews from critics, who commended Adele's vocal performance and the album's production.
