"Heart of Glass" is a song and single from the 1978 album, "Parallel Lines", by Blondie. The album was released on Chrysalis Records (EMI) and was produced by Mike Chapman. The album has sold over 20 million copies worldwide and is the band's most successful release. Six of the album's tracks were released as singles, including the big hit "Heart of Glass".
"Heart of Glass" was written by Deborah Harry and Chris Stein and produced by Mike Chapman. The single was released in January 1979 on Chrysalis Records and was a #1 hit in many countries, including the UK and the U.S.
This video version of "Heart of Glass" is not seen as often as the Studio 54 version and makes an interesting comparison, especially regarding Deborah Harry's appearance.
