Eurythmics (often incorrectly referred to as "The Eurythmics") is a British musical duo, formed in 1980 by Annie Lennox and Dave Stewart.

The pair have achieved significant global, commercial and critical success, selling 75 million records worldwide, winning numerous awards, and have undertaken several successful world tours. They are noted for their intelligent pop songs, which showcase Lennox's powerful and expressive alto voice, and Stewart's innovative production techniques. They are also acclaimed for their promotional videos and visual presentation.

The pair had first worked together as members of The Tourists. During this time, they were also romantic partners. This band achieved modest commercial success, but the experience was reportedly an unhappy one. Personal and musical tensions existed within the group, whose main songwriter was Pete Coombes, the band often received very negative critical press in the UK, and there were legal wranglings with the band's management, publishers and record labels. Lennox and Stewart felt the fixed band line-up was not a good vehicle to explore their experimental creative leanings. Lennox and Stewart decided their next project should be much more flexible and free from artistic compromise. They were interested in creating 'pop music', but wanted freedom to experiment with electronics and the avant-garde as well. Calling themselves "Eurythmics" after a dance technique (Eurythmy; see also Eurhythmics) Lennox had encountered as a child at her school, they decided to keep themselves as the only permanent members and songwriters, and involve others in the collaboration as they saw fit "on the basis of mutual compatibility and availability". RCA Records decided to retain the pair from their Tourists recording contract. Wanting to concentrate on their musical relationship, Lennox and Stewart decided to discontinue their romantic liaison in 1980 (see 1980 in music).

Their first album saw them continue to work in Cologne with the legendary Conny Plank (who had produced the later Tourists sessions). This resulted in the album In the Garden, released October 1981), including contributions from Holger Czukay and Jaki Liebezeit of Can, drummer Clem Burke of Blondie, Robert Görl of Deutsch Amerikanische Freundschaft, and flautist Tim Wheater. A couple of the songs were co-written by guitarist Roger Pomphrey (now a TV director). The album featured rather cold and melancholy songs, mixing psychedelic, krautrock and electropop influences. It received a lukewarm critical reception and poor sales. Two singles from the album also flopped, though "Never Gonna Cry Again" made the UK charts. Lennox and Stewart then put their new Eurythmics mode of operation into action by touring the record as a duo, accompanied by backing tracks and electronics, carted around the country themselves in a horse-box. Eurythmics' commercial breakthrough came with Sweet Dreams (Are Made of This) (1983 in music), whose hit single of the same name featured a dark, powerfully sequenced synth bass line and a striking video that introduced the orange crew cut Lennox sported to fame. The band's fortunes changed immensely from this moment on. The album became a huge British hit due to the title track, which quickly topped the American charts as well. Lennox was featured on the cover of Rolling Stone magazine. Stewart recently revealed that the famous synth bass line in the song was discovered by accident when he inadvertently played a track backwards. "Love Is A Stranger" was re-released and became a hit in its own right. The "Love Is A Stranger" video saw Lennox in many different character guises, which she later became known for in subsequent videos ("Beethoven" and "The King & Queen of America" among them). The album's working title was Invisible Hands (as was a track left off the album), inspiring the name of UK indie label Invisible Hands Music - known for releasing music by Hugh Cornwell, Mick Karn and Hazel O'Connor.
