Around late-'83/early-'84, a group called Discipline took shape in Pittsburgh, PA; transitioning from playing covers into an original hard rock/metal outfit. Discipline laid down a two-song demo that gained local momentum via the Pittsburgh Steel radio show before disbanding in 1985, at which time the remaining members—founder Doug Appel (guitar), Mark Menold (guitar), and Ned Lyden (drums)—joined forces with two former members of another Pittsburgh act called Overlord—bassist David Kendrick and vocalist Tim Aymar (later of Pharaoh, Control Denied, Psycho Scream, Triple X, and many more)—and thus 313 was born.
