"Heart of Glass" is a song by the American new wave band Blondie, written by singer Debbie Harry and guitarist Chris Stein, and produced by Mike Chapman. It was featured on the band's third studio album, Parallel Lines (1978), and was released as the album's third single in January 1979 by Chrysalis Records, reaching number one on the charts in several countries, including the US Billboard Hot 100 and the UK Singles Chart. with sales of 1.32 million copies, being the 9th best selling single of the 1970s in the UK. It was inducted into the Grammy Hall of Fame as a recording of "qualitative or historical significance" in 2015. Harry herself stated that "Heart of Glass" was, along with "Rapture," the song she was proudest of having written.
In December 2004, Rolling Stone ranked the song number 255 on its list of the 500 greatest songs of all time. It was ranked at number 259 when the list was updated in April 2010 and at number 138 in their 2021 update. Slant Magazine placed it at number 42 on their list of the greatest dance songs of all time and Pitchfork named it the 18th best song of the 1970s. Billboard magazine included "Heart of Glass" in their lists of the best pop songs and dance songs of all time in 2023 and 2025.
Harry and Stein sold their future royalties to the song and the rest of Blondie's catalog to Hipgnosis Songs Fund in 2020.
Background
Debbie Harry and Chris Stein wrote an early version of "Heart of Glass", called "Once I Had a Love", in 1974–75. This earlier version was initially recorded as a demo in 1975. The song had a slower, funkier sound with a basic disco beat. For this reason the band referred to it as "The Disco Song". This original version was inspired by The Hues Corporation's hit disco song "Rock the Boat" (1974). The song was re-recorded in a second demo with the same title in 1978, when the song was made a bit more pop-oriented. Harry said that "'Heart of Glass' was one of the first songs Blondie wrote, but it was years before we recorded it properly. We'd tried it as a ballad, as reggae, but it never quite worked", and that "the lyrics weren't about anyone. They were just a plaintive moan about lost love." As a band, Blondie had experimented with disco before, both in the predecessors to "Heart of Glass" and in live cover songs that the band played at shows. Bassist Gary Valentine noted that the set list for early Blondie shows often included disco hits such as "Honey Bee" or "My Imagination". The song's eventual title was taken from the 1976 film of the same name by Werner Herzog, although none of the group had actually seen the movie. As noted by Bob Stanley, the track "blended NYC punk stance with sleek sequenced disco at a time when the two forms were still seen to be diametrically opposed".
In an interview published in the February 4, 1978, edition of NME, Debbie Harry expressed her affinity for the Euro disco music of Giorgio Moroder, stating that "It's commercial, but it's good, it says something... that's the kind of stuff that I want to do". A notable example of this type of musical experimentation occurred when Blondie covered Donna Summer's "I Feel Love" at the Blitz Benefit on May 7, 1978. In his history of CBGB, music writer Roman Kozak described this event: "When Blondie played for the Johnny Blitz benefit in May 1978, they surprised everyone with a rendition of Donna Summer's 'I Feel Love'. In the middle of the great rock versus disco split, it was arguably the first time in New York that a rock band had played a disco song. Blondie went on to record 'Heart of Glass,' other groups recorded other danceable songs, and dance rock was born."
For the single release, Chapman remixed the track, with the double-tracked bass drum further accentuated.
In reflecting on the development of "Heart of Glass" from its earliest incarnations until the recorded version on Parallel Lines, Chris Stein noted that the earliest versions had a basic conventional disco beat, but that the recorded version incorporated the electronic sound of Euro disco, stating that "The original arrangement of 'Heart of Glass'—as on the [1975] Betrock demos—had doubles on the high-hat cymbals, a more straight-ahead disco beat. When we recorded it for Parallel Lines we were really into Kraftwerk, and we wanted to make it more electronic. We weren't thinking disco as we were doing it; we thought it was more electro-European."
Production
"Heart of Glass" was recorded at the Record Plant in New York City in June 1978. The production of "Heart of Glass" was discussed in detail by Richard Allinson and Steve Levine on the BBC Radio 2 radio program The Record Producers that was aired on May 25, 2009. As explained in the program, the production of "Heart of Glass" was built around the use of a Roland CR-78 drum machine. The CR-78 was first introduced in 1978, the same year that Parallel Lines was recorded, and the use of this device on "Heart of Glass" was, according to the program, among the earliest uses of this device in popular music. As the program explained, using a drum machine in the context of a rock band was also very unusual.
In deciding to use the CR-78 for "Heart of Glass", the choice was made to combine the sound of the drum machine with the sound of actual drumming. This reflected the hybrid nature of the song, the combination of a drum machine that was typically used in the context of dance music with the actual drum sound that was a traditional aspect of rock recordings. In combining these elements, the sound of the drum machine was first recorded on an individual track. To synchronize the actual drum play with the drum machine, the drums were also recorded on separate tracks, with the bass drum recorded separately from the rest of the drums.
Having combined the drums with the drum machine, another important feature of the CR-78 was that it could be used to send a trigger pulse to the early polyphonic synthesizers. This trigger pulse feature was also used on "Heart of Glass". The trigger pulse created by the CR-78 became a distinctive electronic/synth element of the song. The additional synthesizer portions of the song were played separately.
Other electronic musical instruments used in the track include the Roland SH-5 and Minimoog synthesizers. Due to the lack of music sequencers, they recorded three different parts using the SH-5 and Minimoog. The original album version was released as a single in the UK where the BBC bleeped out the word "ass". Debbie Harry told The Guardian, "At first, the song kept saying: 'Once I had a love, it was a gas. Soon turned out, it was a pain in the ass.' We couldn't keep saying that, so we came up with: 'Soon turned out, had a heart of glass.' We kept one 'pain in the ass' in – and the BBC bleeped it out for radio." and reached only No. 58 in Billboards Disco Top 80 chart. One of the first rock/disco fusion hits, it was more popular in rock-oriented nightclubs such as Hurrah and the Mudd Club. Record World said that it "could create a new audience for the group." Billboard, Paste and The Guardian all named "Heart of Glass" as Blondie's best song.
Blondie re-recorded the song for the 2014 2-disc set Blondie 4(0) Ever.
"Heart of Glass" was re-released in 2018 as a 6-track EP in promotion of Blondie's archive collection box set Against the Odds 1974–1982.
Controversy
At the time, Blondie was one of the bands at the forefront of New York's growing new wave music scene. The band was accused of "selling out" for releasing a disco song. According to Harry, "Heart of Glass" made the band pariahs in the eyes of many of their fellow musicians in the New York music scene. The band was accused of pandering to the mainstream that many punk/new wave bands at the time were actively rebelling against. She also said, "People got nervous and angry about us bringing different influences into rock. Although we'd covered 'Lady Marmalade' and 'I Feel Love' at gigs, lots of people were mad at us for 'going disco' with 'Heart of Glass'... Clem Burke, our drummer, refused to play the song live at first. When it became a hit, he said: 'I guess I'll have to.'" Chris Stein was unrepentant about the song's disco sound, saying, "As far as I was concerned, disco was part of R&B, which I'd always liked."
Music video
The "Heart of Glass" music video was directed by Stanley Dorfman. Contrary to popular belief, it was not filmed at the Studio 54 nightclub; Chris Stein said that "in the video, there's a shot of the legendary Studio 54, so everyone thought we shot the video there, but it was actually in a short-lived club called the Copa or something". To create the dress, Sprouse photo-printed a picture of television scan lines onto a piece of fabric, and then, according to Harry, "put a layer of cotton fabric underneath and a layer of chiffon on top, and then the scan-lines would do this op-art thing." The popularity of the song helped Sprouse's work earn a lot of exposure from the media. Harry also said that the T-shirts used by the male members of the band in the video were made by herself. Reviewing the 2005 Greatest Hits: Sound & Vision DVD for Pitchfork, Jess Harvell wrote that while "owning your own copy of 'Heart of Glass' may not seem as cool [anymore]... there's the always luminous Deborah Harry, who would give boiling asparagus an erotic charge, all while looking too bored to live."
