Formed at ground zero of Boston's legendary straight edge hardcore scene, DYS rose out of SS Decontrol's Boston Crew, going on to help establish the city as a center of the movement along with Negative FX and Last Rights.

Their debut album "Brotherhood" was released by SSD's X-Claim records, recorded at legendary 8-track Boston studio Radiobeat, and produced by Lou Giordano who went on to work with Husker Du. The album cover was designed and drawn by future Mighty, Mighty Bosstone Dickie Barrett, an early fan and friend. "Brotherhood" was classic old-school thrash, with lyrics dedicated to straight edge values and personal politics. Original pressings sell on ebay today for over $200.

Adding a second guitar player, DYS progressed into early Metal Crossover with their self-titled second album. Released on Modern Method (and produced - to the shock of Hardcore purists - by Al Long and Done Foote who were members of electronic dance act "November Group"). DYS was one of the first Hardcore records to explore modern 24 track recording techniques, and digitial effects as well as de-tuning, multi-part, multi-tempoed songs and other alternative metal influences heard later on other period records like Metallica's "Kill 'em All" and the Cro-Mags "Age of Quarrel." Live sound was handled by the now-legendary Mudrock, producer of the Godsmack and Avenged Sevenfold Records.

Taang! Records subsequently released both albums in various formats and collections with current versions still in print.

Singer Dave Smalley went on to form early emo-pop-hardcore band Dag Nasty with Brian Baker from Minor Threat as well as All, Down by Law and the Sharp Shooters. Bassist Jonathan Anastas helped form second generation hardcore legends Slapshot, writing and playing on their debut record "Back on the Map."
