Sufjan Stevens (pron-en?su?fj??n respellSOOFyahn; born July 1, 1975) is an American singer-songwriter and musician born in Detroit, Michigan. Stevens first began releasing his music on the Asthmatic Kitty label, a label he formed with his stepfather, beginning with the 2000 release A Sun Came. He is best known for his 2005 album Illinois (Illinois (album)), which hit number one in the Billboard (Billboard charts) Top Heatseekers chart, and for the song "Chicago".

Stevens has released albums of varying styles, from the electronica of Enjoy Your Rabbit and the lo-fi folk (folk music) of Seven Swans to the symphonic instrumentation of Illinois and Christmas-themed Songs for Christmas. Stevens makes use of a variety of instruments, often playing many of them himself on the same track, and writes music in various time signatures. He is considered part of the folk (folk music) revival in indie pop, but his influences are very broad. His music has been likened to electronica (ambient music)cite web first = Louis last = Pattison title = Avalanche Review publisher = Amazon.co.uk url = quote = Part psychedelic bluegrass, part extra-terrestrial electronic ambience, and part tribal percussion-fest accessdate = 2006-11-29 and aesthetically compared to the minimalism (Minimalist music) of Steve Reich.cite web last = Gill first = Andy title = Illinois Review publisher = Uncut url = accessdate = 2006-11-29 quote = All rendered in a weird, pan-stylistic blend of alt.country, minimalism and American brass band music Stevens music often has spiritual themes, and many songs (most notably on Seven Swans) draw inspiration from Bible (Biblical) stories.

Stevens has garnered much interest from the press for his "Fifty States Project", his aim being to complete an album about each of the states of the United States. Stevens has thus far completed two state records, Illinois (Illinois (album)) and his home state record Michigan (Michigan (album)). He stated in 2005 that he remained serious about its completion, but more recently that the idea was "such a joke".
