Dillinger Escape Plan tore up a sold-out crowd with an intimate warmup gig at Highland Park's Hi Hat on Monday, Aug. 15. In 1997 D.E.P. released their first EP; now, 20 years later, they're releasing what will become their final album, Dissociation, on Oct. 14. When D.E.P. call it quits after this touring cycle, the heavy music scene will be losing possibly its most powerful live act.
