Brian Baker, formerly of Minor Threat, formed Dag Nasty with Colin Sears, Roger Marbury and Shawn Brown in 1985. Shawn's replacement on vocals (by ex- DYS frontman Dave Smalley) shortly before the recording of their debut full-length, Can I Say, began a revolving door membership that was to continue throughout their duration as a band (ultimately leaving Brian as the only original member.) Dag Nasty recorded Can I Say in June 1986, and Wig Out at Denkos in July 1987, for Dischord Records before moving to Giant Records for the release of Field Day in 1988.
