I. Minor Threat/D.C Scene

Minor Threat was a hardcore punk band that formed in Washington D.C. in 1980 and lasted until 1983.

The heavy influence they had in their DIY ethics, as well as creating the term "Straight Edge" plus being the origins of the moment (which stands for a clean lifestyle: no drugs, no drinking)

The band was fronted by Ian MacKaye, whom promoted DIY ethics and took it to the step of starting his own label Dischord Records in 1980. This helped promote the D.C. hardcore scene which spawned tons of heavily influential bands including Bad Brains, Rites of Spring (who will become important in a second), as well as Black Flag singer Henry Rollins.
