S-21 are one of Philadelphia’s best hardcore punk outfits making music right now. With their “Year Zero” EP, they’ve drummed up four new songs that are a natural follow-up to the four tracks on their demo tape. S-21 create mid-tempo punk with pummeling riffs and powerful vocal delivery. Four cuts to stomp around to. Pocket sleeve and two-sided insert. Co-released with World Gone Mad (each label with 200 copies).
