Den of Iniquity is a massive, 23-song collection of rare tracks spanning "The Melnick Era" (1988-1998) of legendary Cleveland hardcore band Integrity. All material is culled from various demos, split 7"s, 7" singles, compilation appearances, and EP's. In short, this is all the hard-to-find non-album stuff of that era. The CD version of the release includes extensive liner notes from guitarist Aaron "A2" Melnick on the recording sessions for each track and exclusive artwork from singer Dwid Hellion.
