Question: Talking Heads were an American rock band formed in 1975 in New York City and active until 1991. The band comprised David Byrne (lead vocals, guitar), Chris Frantz (drums), Tina Weymouth (bass), and Jerry Harrison (keyboards, guitar). Described by critic Stephen Thomas Erlewine as "one of the most critically acclaimed bands of the '80s", the group helped to pioneer new wave music by integrating elements of punk, art rock, funk, and world music with avant-garde sensibilities and an anxious, clean-cut image. Former art school students, who became involved in the 1970s New York punk scene, Talking Heads released their debut

After releasing four albums in barely four years, the group went into hiatus, and nearly three years passed before their next release, although Frantz and Weymouth continued to record with the Tom Tom Club. In the meantime, Talking Heads released a live album The Name of This Band Is Talking Heads, toured the United States and Europe as an eight-piece group, and parted ways with Eno, who went on to produce albums with U2. 1983 saw the release of Speaking in Tongues, a commercial breakthrough that produced the band's only American Top 10 hit, "Burning Down the House". Once again, a striking video was inescapable owing to its heavy rotation on MTV. The following tour was documented in Jonathan Demme's Stop Making Sense, which generated another live album of the same name. The tour in support of Speaking in Tongues was their last. Three more albums followed: 1985's Little Creatures (which featured the hit singles "And She Was" and "Road to Nowhere"), 1986's True Stories (Talking Heads covering all the soundtrack songs of Byrne's musical comedy film, in which the band also appeared), and 1988's Naked. Little Creatures offered a much more American pop-rock sound as opposed to previous efforts. Similar in genre, True Stories hatched one of the group's most successful hits, "Wild Wild Life", and the accordion-driven track "Radio Head", which became the etymon of the band of the same name. Naked explored politics, sex, and death, and showed heavy African influence with polyrhythmic styles like those seen on Remain in Light. During that time, the group was falling increasingly under David Byrne's control and, after Naked, the band went on "hiatus". It took until December 1991 for an official announcement to be made that Talking Heads had broken up. Their final release was "Sax and Violins", an original song that had appeared earlier that year on the soundtrack to Wim Wenders' Until the End of the World. During this breakup period, Byrne continued his solo career, releasing Rei Momo in 1989 and The Forest in 1991. This period also saw a revived flourish from both Tom Tom Club (Boom Boom Chi Boom Boom and Dark Sneak Love Action) and Harrison (Casual Gods and Walk on Water), who toured together in the summer of 1990.
