Depeche Mode are an English electronic band formed in Basildon, Essex in 1980. The group consists of founders Dave Gahan (lead vocals, co-songwriting), Martin Gore (keyboards, guitar, chief songwriting), and Andy Fletcher (keyboards). Depeche Mode released their debut album Speak & Spell in 1981, bringing the band onto the British new wave scene. Original band member Vince Clarke, left the band after the release of the album, leaving the band as a trio to record A Broken Frame, released the following year.

During the touring and promotion for Speak & Spell, Clarke privately began to voice his discomfort at the direction the band was taking. He later expressed his dissatisfaction, saying "there was never enough time to do anything. Not with all the interviews and photo sessions". In November 1981, Clarke publicly announced that he was leaving Depeche Mode. It was also claimed that Clarke was sick of touring, which Gahan said years later was "bullshit to be quite honest". Gahan went on to say he "suddenly lost interest in it and he started getting letters from fans asking what kind of socks he wore".  Soon afterwards, Clarke joined up with blues singer Alison Moyet to form Yazoo (or Yaz in the United States). Initial talk of Clarke's continuing to write material for Depeche Mode ultimately amounted to nothing. According to third-party sources, Clarke offered the remaining members of Depeche Mode the track "Only You", but they declined. Clarke, however, denied in an interview that such an offer ever took place saying, "I don't know where that came from. That's not true." The song went on to become a UK Top 3 hit for Yazoo. Gore, who had written "Tora! Tora! Tora!" and the instrumental "Big Muff" for Speak & Spell, became the band's main lyricist.  In late 1981, the band placed an anonymous ad in Melody Maker looking for another musician: "Name band, synthesise, must be under twenty-one." Alan Wilder, a classically trained keyboardist from West London, responded and, after two auditions and despite being 22 years old, was hired in early 1982, initially on a trial basis as a touring member. Wilder would later be called the "Musical Director" of the band, responsible for the band's sound until his departure in 1995. As producer Flood would say, "[Alan] is sort of the craftsman, Martin's the idea man and [Dave] is the attitude."  In January 1982, the band released "See You", their first single without Clarke, which managed to beat all three Clarke-penned singles in the UK charts, reaching number six. The following tour saw the band playing their first shows in North America. Two more singles, "The Meaning of Love" and "Leave in Silence," were released ahead of the band's second studio album, on which they began work in July 1982. Daniel Miller informed Wilder that he was not needed for the recording of the album, as the core trio wanted to prove they could succeed without Vince Clarke. A Broken Frame was released that September, and the following month the band began their 1982 tour. A non-album single, "Get the Balance Right!," was released in January 1983, the first Depeche Mode track to be recorded with Wilder.
