During 1999, D.R.I. appeared as one of the headlining bands on the "Social Chaos" in North America Tour. One of their songs, "I'm The Liar", is used for a Social Chaos Tour CD compilation. The CD contained one song from each band that appeared on the tour. During August 1999, in the middle of the tour, Chumly left the band after tiring of touring. He was replaced by Harald Oimoen. Oimoen had been working on and off with the band for years, doing everything from photography and merchandise to bass tech. The band resumed the tour missing only two shows.
