1978 · Behind the Songs
Disco, new wave, and a controversial hit.
“Heart of Glass” (1978), from Parallel Lines, mixed disco with new wave and became a global hit, even though it caused controversy in the punk community that had first supported Blondie. The song’s shimmering keyboards, steady disco beat and Harry’s cool vocal made it sound both polished and distant, like a dance song heard through glass. That distance is the point of the title: a heart that looks clear and bright, but breaks easily.
The controversy faded, but the song’s importance did not. It proved that a band from CBGB could make a disco record without losing its identity, and it opened the door for Blondie to move beyond punk into pop. Heard today, “Heart of Glass” still sounds modern, because it never fully commits to either disco or rock — it lives in the space between them, and that space is where Blondie did their best work.
