Mark Edward Kozelek (born January 24, 1967) is an American singer, songwriter, guitarist, record producer and occasional actor. He is best known as the vocalist and primary recording artist of the indie folk act Sun Kil Moon, with whom he has recorded eight studio albums, and as the vocalist, guitarist and founding member of the indie rock band Red House Painters, with whom he recorded six studio albums from 1989 until 2001.

Born and raised in Massillon, Ohio, Kozelek developed an interest in music as a child. Upon meeting drummer Anthony Koutsos in Atlanta, Georgia, the pair moved to San Francisco, California and formed Red House Painters alongside guitarist Gorden Mack and bass guitarist Jerry Vessel. Signing with record label 4AD, the band released four studio albums to critical acclaim. In 1996, Kozelek recorded the band’s fifth studio album, Songs for a Blue Guitar, mostly alone. The release of the band’s final studio album, Old Ramon (2001), was delayed for three years. In the interim, Kozelek recorded both an album and an EP of AC/DC cover songs.

Reconvening with Koutsos and Vessel, the trio continued performing under the new name of Sun Kil Moon, releasing their debut album, Ghosts of the Great Highway, in 2003. Inspired by classical guitar music, Kozelek recorded Sun Kil Moon’s fourth studio album, Admiral Fell Promises (2010), as a solo act, and continued to record mostly alone on its follow-up, Among the Leaves (2012). The album introduced a deeply personal lyrical perspective, which continued on the collaborative solo releases, Perils from the Sea and Mark Kozelek & Desertshore, both released in 2013.

In 2014, Sun Kil Moon’s sixth studio album, Benji, was released to widespread critical acclaim and increased exposure, with its follow-up, Universal Themes, featuring lengthy compositions and stream-of-consciousness lyrics. In 2016, Kozelek released a collaborative studio album with Jesu, titled Jesu/Sun Kil Moon.

Across his work in Sun Kil Moon, Red House Painters and his own solo material, Kozelek has released twenty-seven studio albums.
