Stevens was born in Detroit, Michigan, and lived there until the age of nine, when his family moved to Petoskey, in the northern part of the Lower Peninsula of Michigan. He was raised by his father Rasjid and his stepmother Pat, only occasionally visiting his mother, Carrie, in Oregon after she married her second husband Lowell Brams. His mother is deceased. Brams later became the head of Stevens' record label Asthmatic Kitty.

In 2010, Stevens was featured on The National's album High Violet, released in May, and sang backing vocals for the band on the Late Show with David Letterman. Following the release of High Violet, band frontman Matt Berninger mentioned that Stevens was recording a new album in the band's studio and that The National would appear on some of the tracks. In early August, Stevens announced North American tour dates across dozens of cities. On August 20, 2010, Stevens suddenly and unexpectedly released a new collection of tracks, the All Delighted People EP, for digital download. The EP is built around two versions of the title track, "All Delighted People." The EP surprisingly rose to #27 on the Billboard 200 albums solely through its digital sales. On August 26, Asthmatic Kitty announced that Stevens would release his newest full-length album, The Age of Adz, on October 12. NPR streamed the album until it was released on October 12, 2010.  The two albums featured a wide range of arrangements, from orchestral to electronic. Song lengths were also extended; the track "Djohariah" from All Delighted People is 17 minutes long, while "Impossible Soul" from The Age of Adz is 25 minutes long. The albums also feature many styles from disco to folk.  Stevens has stated in interviews that in 2009/10, he suffered from a mysterious debilitating virus infection that affected his nervous system. He experienced chronic pain and was forced to stop working on music for several months. He said: "The Age of Adz, is, in some ways, a result of that process of working through health issues and getting much more in touch with my physical self. That's why I think the record's really obsessed with sensation and has a hysterical melodrama to it."  On October 12, 2010, Stevens began his North American tour in Montreal, featuring virtually all new material. The tour lasted just over a month and ended on November 15, 2010 in New York City.  Stevens toured Australia and New Zealand in early 2011, featured as part of the Sydney Festival, and appeared on-stage with The National during the last of three sold-out Auckland shows. He also toured Europe and the United Kingdom in April and May 2011, playing there for the first time in five years. His shows mostly consisted of new material, but he did play many older tracks from Seven Swans and Illinois. Stevens ended the Age of Adz tour with two shows in Prospect Park, Brooklyn, New York.
