A influential punk band in the 80's. They were instrumental in the formation of the DC HarDCore scene in Washington, DC. The band was fronted by Ian MacKaye and included Brian Baker on bass, Lyle Preslar on guitar, and Jeff Nelson on drums. The band is probably most famous for the song 'Straightedge'. MacKaye currently fronts Fugazi, and Baker plays in Bad Religion.
Dude, Minor Threat were an amazing example of DC HarDCore.
