Dag Nasty, the melodic hardcore band from D.C. credited with (or accused of) paving the way for emocore, is planning to reunite for one magical evening at the Black Cat Dec. 28.

The reunion will include original members Shawn Brown, Brian Baker, Roger Marbury, and Colin Sears, the lineup that wrote much of Dag Nasty’s well-loved debut LP Can I Say, released in 1986 on Dischord Records. (It’s being called the Can I Say lineup, but vocalist Dave Smalley actually sang on the band’s first record.)

Reunion-happy Government Issue is also on the bill, alongside Black Market Baby and Kingface. (Related: Check out Mike Paarlberg‘s July 2011 City Paper story about hardcore-band reunions.)

The show is a “celebration” of Salad Days, Scott Crawford‘s forthcoming documentary about D.C.’s 1980s hardcore scene. (The Kickstarter for that film, by the way, has met and exceeded its original goal of $32,000; the goal has since been bumped up to $42,000.)

The original version of this post inaccurately reported that Shawn Brown sang on Dag Nasty’s Can I Say. Dave Smalley was the vocalist on that record.
