The song that burst Blondie out of the streets of the Bowery to #1 on the charts, "Heart of Glass" was the pivotal moment in punk's choreographed slamdance with the mainstream. Inspired by Kraftwerk and Giorgio Moroder, Blondie transformed their campy "Disco Song" into a Roland-driven juggernaut and never looked back. Explored and exploded via six distinct versions remastered from the original analog tapes, the history of "Heart of Glass" is documented here in a copious essay and it's art reimagined by noted American illustrator Shepard Fairey.
