Background: 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.
Context: 1987's Music for the Masses saw further alterations in the band's sound and working methods. For the first time a producer not related to Mute Records, Dave Bascombe, was called to assist with the recording sessions, although, according to Alan Wilder, Bascombe's role ended up being more that of engineer. In making the album, the band largely eschewed sampling in favour of synthesizer experimentation. While chart performance of the singles "Strangelove", "Never Let Me Down Again" and "Behind the Wheel" proved to be disappointing in the UK, they performed well in countries such as Canada, Brazil, West Germany, South Africa, Sweden and Switzerland, often reaching the top 10. Record Mirror described Music for the Masses as "the most accomplished and sexy Mode album to date". The album also made a breakthrough in the American market.  The Music for the Masses Tour began 22 October 1987. On 7 March 1988, with no previous announcement that they would be the headlining act, Depeche Mode played in the Werner-Seelenbinder-Halle, East Berlin, becoming one of the few Western groups to perform in the Communist East Germany. They also performed concerts in Budapest and Prague in 1988, both at the time also Communist.  The world tour ended 18 June 1988 with a concert at the Pasadena Rose Bowl with paid attendance of 60,453, the highest in eight years for the venue. The tour was a breakthrough for the band and a massive success in the United States. It was documented in 101 - a concert film by D. A. Pennebaker and its accompanying soundtrack album. The film is notable for its portrayal of fan interaction. Alan Wilder is credited with coming up with the title, noting that the performance was the 101st and final performance of the tour. On 7 September 1988, Depeche Mode performed "Strangelove" at the 1988 MTV Video Music Awards at the Universal Amphitheatre in Los Angeles.
