Unknown Pleasures is the debut studio album by English rock band Joy Division, released on 15 June 1979 by Factory Records.[1] The album was recorded and mixed over three successive weekends at Stockport's Strawberry Studios in April 1979, and was produced by Martin Hannett,[1] who incorporated a number of unconventional production techniques into the group's sound. The cover artwork was designed by artist Peter Saville, using a data plot of signals from a radio pulsar.[2] It is the only Joy Division album released during lead singer Ian Curtis's lifetime.
