"What's On Your Mind? (Pure Energy)" is a music single by dance artists Information Society which was released in 1988. The "Pure Energy" subtitle derives from a sample of Leonard Nimoy's voice from the Star Trek episode "Errand of Mercy".
Information Society (also known as InSoc) is a U.S. band originally from Minneapolis, Minnesota, primarily consisting of Kurt Larson (aka Kurt Valaquen/Kurt Harland), Paul Robb, and James Cassidy; the latter two reconvened the band in 2006. Their breakout hit was 1988's "What's On Your Mind? (Pure Energy)", a dance hit which included a 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!"
