Henry Lawrence Garfield (born February 13, 1961), better known by his stage name Henry Rollins, is an American musician, actor, writer, television and radio host, and comedian. He hosts a weekly radio show on KCRW, and is a regular columnist for Rolling Stone Australia and was a regular columnist for LA Weekly. After performing in the short-lived Washington, D.C. band State of Alert in 1980, Rollins fronted the California hardcore punk band Black Flag from August 1981 until mid-1986. Following the band's breakup, Rollins established the record label and publishing company 2.13.61 to release his spoken word albums, and formed the Rollins Band, which toured with a number of lineups from 1987 until 2003, and during 2006.

On May 19, 2004, Rollins began hosting a weekly radio show, Harmony in My Head, on Indie 103.1 radio in Los Angeles. The show aired every Monday evening, with Rollins playing music ranging from early rock and jump blues to hard rock, blues rock, folk rock, punk rock, heavy metal and rockabilly, and touching on hip hop, jazz, world music, reggae, classical music and more. Harmony in my Head often emphasizes B-sides, live bootlegs and other rarities, and nearly every episode has featured a song either by the Beastie Boys or British group The Fall. Rollins put the show on a short hiatus to undertake a spoken-word tour in early 2005. Rollins posted playlists and commentary on-line; these lists were expanded with more information and published in book form as Fanatic! through 2.13.61 in November 2005. In late 2005, Rollins announced the show's return and began the first episode by playing the show's namesake Buzzcocks song. In 2008, the show was continuing each week despite Rollins's constant touring with new pre-recorded shows between live broadcasts. In 2009, Indie 103.1 went off the air, although it continues to broadcast over the Internet. In 2007, Rollins published Fanatic! Vol. 2 through 2.13.61. Fanatic! Vol. 3 was released in the fall of 2008. On February 18, 2009, KCRW announced that Rollins would be hosting a live show on Saturday nights starting March 7, 2009, which has since been moved to Sunday nights at 8PM. In 2011 Rollins was interviewed on Episode 121 of American Public Media's podcast, "The Dinner Party Download", posted on November 3, 2011.
