Producer Martin Hannett "dedicated himself to capturing and intensifying Joy Division's eerie spatiality". Hannett believed punk rock was sonically conservative because of its refusal to use studio technology to create sonic space. The producer instead aimed to create a more expansive sound on the group's records. Hannett said, "Division were a gift to a producer, because they didn't have a clue. They didn't argue". Hannett demanded clean and clear "sound separation" not only for individual instruments, but even for individual pieces of Morris's drumkit. Morris recalled, "Typically on tracks he considered to be potential singles, he'd get me to play each drum on its own to avoid any bleed-through of sound". Music journalist Richard Cook noted that Hannett's role was "crucial". There are "devices of distance" in his production and "the sound is an illusion of physicality".
