Information Society (also known as InSoc) is an American band originally from Minneapolis, Minnesota, initially active from 1982 to 1997, primarily consisting of Kurt Harland, Paul Robb, and James Cassidy; the latter two reconvened the band in 2006, initially with Christopher Anton as lead vocalist, then with Harland rejoining them as lead vocalist by 2008. The group's breakout hit was 1988's "What's on Your Mind (Pure Energy)", a synthpop/freestyle hit, which spent 39 weeks on the dance chart, going straight to No. 1, and would also peak at No. 3 on the Hot 100 pop chart. The track included a vocal sample of Mr. Spock (Leonard Nimoy) from Star Trek, saying "pure energy", and opened with a sample of Dr. McCoy (DeForest Kelley), also from Star Trek, saying, "It's worked so far, but we're not out yet!" The samples are from Star Trek episodes "Errand of Mercy" and "I, Mudd", respectively. The sample of Captain Kirk saying, "In every revolution there is one man with a vision," occurs at the beginning of "Over the Sea." The group is known for its loyal fan base in Brazil, Japan, Spain, and Mexico. Information Society became part of the American response to the Second British Invasion and often called "Imitation Society."
