 On "Bulldozer", Big Black's founder and frontman Steve Albini achieved a signature "clanky" sound with his guitar by using metal guitar picks notched with sheet metal clips, creating the effect of two guitar picks at once.The "Bulldozer" EP was recorded with engineer Iain Burgess and released in December 1983, with the first two hundred copies packaged in a galvanized sheet metal sleeve in homage to Public Image Ltd.'s "Metal Box".Many of the EP's lyrics depicted scenarios drawn from Albini's midwest upbringing, such as "Cables", which described the slaughtering of cows at a Montana abattoir, and "Pigeon Kill", about a rural Indiana town that dealt with an overpopulation of pigeons by feeding them poisoned corn.
