Eurythmics' commercial breakthrough came with their second album, "Sweet Dreams (Are Made of This)", released in January 1983. The successful title track featured a dark and powerful sequenced synth bass line and a dramatic video that introduced the now orange crew-cut Lennox to audiences. The song reached No. 2 on the UK Singles Chart, becoming one of the year's biggest sellers, and later topped the US "Billboard" Hot 100. The band's fortunes changed immensely from this moment on, and Lennox quickly became a pop icon, gracing the covers of numerous magazines including "Rolling Stone". Their previous single, "Love Is a Stranger", was also re-released and became another chart success. The video for the song saw Lennox in many different character guises, a concept she would employ in various subsequent videos. The album's working title was "Invisible Hands" (as was a track left off the album), inspiring the name of the British independent company Invisible Hands Music – known for releasing music by Hugh Cornwell, Mick Karn and Hazel O'Connor. The album also featured a cover of the 1968 Sam & Dave hit "Wrap It Up", performed as a duet between Lennox and Green Gartside of Scritti Politti.
