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.

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 packaged in gorgeous screened and die cut sleeve.
