DYS was a straight edge, hardcore punk and heavy metal band from Boston, Massachusetts, and part of the notorious "Boston Crew" along with contemporaries such as SSD and Negative FX. They released two LPs: Brotherhood, an album produced by legendary punk producer Lou Giordano and still held in high regard by fans of hardcore music (with original copies selling for in-excess of $150 on ebay), and DYS (i.e., self-titled), an album that is more a hard rock or heavy metal album than a hardcore album.
