“Atmosphere”, produced by Martin Hannett, was originally released in March 1980 on record label Sordide Sentimental as “Licht und Blindheit” (“Light and Blindness”), a France-only limited edition single featuring the track “Dead Souls” as the B-side. Following Ian Curtis’s death two months later, it was re-released as a 12″ single by record label Factory with “She’s Lost Control” as the B-side.
