30 is the fourth studio album by English singer-songwriter Adele. It was released on 19 November 2021 by Columbia Records, as Adele's first studio album since 25 (2015). 30 is inspired by Adele's divorce, motherhood, fame, and heartache, and expresses themes of acceptance and hope. She wrote the album from 2018 through 2020 with producers such as Greg Kurstin, Max Martin and Shellback, all of whom worked on 25 as well. New collaborators included Ludwig Göransson, and Inflo of English band Sault.
Musically, 30 is a pop, soul, and jazz album. Journalists have described it as Adele's most creative work sonically, expanding on her past works by incorporating dance-pop, gospel and jazz elements. American jazz pianist Erroll Garner appears on the track "All Night Parking" as a guest act, marking the first time an artist is featured on a standard album by Adele. The lead single, "Easy on Me", was released on 15 October 2021 and topped the charts in 27 territories. An extensive marketing campaign was used to promote 30, including Adele One Night Only in the US and An Audience with Adele in the UK.
