Minor Threat was an American hardcore punk band, formed in 1980 in Washington, D.C., by vocalist Ian MacKaye and drummer Jeff Nelson. MacKaye and Nelson had played in several other bands together, and recruited bassist Brian Baker and guitarist Lyle Preslar to form Minor Threat. They added a fifth member, Steve Hansgen, in 1982, playing bass, while Baker switched to second guitar.

Straight edge is a subculture of hardcore punk whose adherents refrain from using alcohol, tobacco and recreational drugs in reaction to the punk subculture's excesses. Some adherents refrain from engaging in casual sex, follow a vegetarian or vegan diet and do not consume caffeine or prescription drugs. The term "straight edge" was adopted from the 1981 song "Straight Edge" by the hardcore punk band Minor Threat.
