Minor Threat - Out Of Step Minor Threat

You may be surprised given their influence that Out of Step is the only album by Washington DC hardcore punk band Minor Threat. They'd already broken up once before recording the album but the band bedded down to make a classic of its genre notable for complex chord progressions and time signatures at odds with the previous more simplistic structures. A now iconic statement of intent before the band splintered off into the likes of Fugazi and Dag Nasty.
