The Flaming Lips are an American rock band formed in 1983 in Oklahoma City, Oklahoma. The group recorded several albums and EPs on an indie label, Restless, in the 1980s and early 1990s. After signing to Warner Brothers, they released their first record with Warner, "Hit to Death in the Future Head" (1992). They later released The Soft Bulletin (1999), which was NME magazine's Album of the Year, and then Yoshimi Battles the Pink Robots (2002).

In 1991, the band started recording their major label debut Hit to Death in the Future Head. The album's release was halted for nearly a year due to the use of a sample from Michael Kamen's score for the film Brazil in the track "You Have to Be Joking (Autopsy of the Devil's Brain)", which required a lengthy clearance process. After the recording of this album Donahue left the band to concentrate on Mercury Rev and Roberts left the band as well, citing creative differences. They were replaced by Ronald Jones and Steven Drozd respectively.  In 1993, they released Transmissions from the Satellite Heart. This was the only studio album since In a Priest Driven Ambulance to date in which Dave Fridmann has not been involved. Because of the success of the album and the single "She Don't Use Jelly", the band was featured on four popular television series: Beverly Hills, 90210, Late Show with David Letterman, Charmed and Beavis and Butt-head. The success of this record led to long stints of touring, opening for bands including the Red Hot Chili Peppers and Candlebox.  Clouds Taste Metallic was released to much critical fanfare in late 1995, though it did not achieve the commercial success of its predecessor. The strain of the year-long Clouds tour, added to the stress from the three years touring in support of Transmissions, was a major factor in the departure of Ronald Jones in late 1996. He was said to be suffering from a severe case of agoraphobia, although the documentary Fearless Freaks states that he left because of his growing concerns over Drozd's drug use.  In September 2014, the Lips paid tribute to former bandmate Ronald Jones and the impact his music had on their developing sound by performing Transmissions from the Satellite Heart live at First Avenue. In February 2015, they performed Clouds Taste Metallic live at the same venue and in December 2015, a 20th Anniversary box set called Heady Nuggs: 20 Years After Clouds Taste Metallic 1994-1997 surrounding the album's release, and the cult status it has achieved over the years was also released.
