Unknown Pleasures is the debut studio album by the English rock band Joy Division, released on 15 June 1979 by Factory Records. The album was recorded and mixed over three successive weekends at Stockport's Strawberry Studios in April 1979, with producer Martin Hannett contributing a number of unconventional recording techniques to the group's sound. The cover artwork was designed by artist Peter Saville, using a data plot of signals from a radio pulsar. It is the only Joy Division album released during lead singer Ian Curtis's lifetime.

Bernard Sumner is an English musician. He is a founding member of the bands Joy Division, New Order, Electronic, and Bad Lieutenant. Sumner was an early force in several areas, including the post-punk, synth-pop, and techno music scenes, as well as their various related genres, and was an early influence on the Manchester music scene that presaged the Madchester movement of the late 1980s centred on Factory Records and The Haçienda club in Manchester.
