Depeche Mode rocked the 80's with their distinct electronic sound and invigorating performances. Depeche Mode released their debut record in 1981, Speak & Spell, bringing the band onto the British new wave scene. The group's original line-up consisted of Dave Gahan (lead vocals, occasional songwriter since 2005), Martin Gore (keyboards, guitar, vocals, chief songwriter after 1981), Andy Fletcher (keyboards), and Vince Clarke (keyboards, chief songwriter from 1980 until 1981). The alterations in songwriting duties indicates the turmoil and turnover the band experienced. The band's last albums of the 1980s, Black Celebration and Music for the Masses, established them as a dominant force on the mainstream electronic music scene. Depeche Mode have sold over 100 million records worldwide.
