Blondie's 'Heart of Glass' is a shimmering gem in the crown of late 70s music, a track that effortlessly melds the raw edge of punk with the hypnotic allure of disco.

Released in 1978 as a track in the band's album, Parallel Lines, it has singer Debbie Harry, along with guitarist Chris Stein, joyfully and laconically embracing a beat - really, a cardiac one - whose beauty lies in its seamless fusion of heartbreak and nonchalance.

Debbie's ethereal vocals float over a pulsating rhythm, creating a soundscape both haunting and exhilarating. The song is a lament about love gone awry, but the lament comes with what seems much-practised and perfected detachment.

The lines, 'If I fear I'm losing you/ it's just/ no good/ You teasing like you do' capture the Anarkali-like fragility and fleeting nature of love with deadly precision.

Musically, the track is a masterclass in production. The use of a Roland Rhythm Machine gives it a distinctive, almost robotic beat, while the lush synths and guitar riffs play a gritty, 20th-century angelic chorus.

It is a song that invites you to lose yourself in its rhythm, to dance away the heartache it so poignantly describes.
