Dag Nasty is an American hardcore punk band from Washington D.C., formed in 1985 by guitarist Brian Baker of Minor Threat, drummer Colin Sears and bassist Roger Marbury, both of Bloody Mannequin Orchestra, and vocalist Shawn Brown. Their style of less aggressive, melodic hardcore was influential to post-hardcore; their sound was partly influenced by The Faith and their 1983 EP Subject to Change. Other influences include Descendents, Buzzcocks, and The Clash.
