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.” The group is known for its loyal fan base in Brazil, Japan, Spain, and Mexico.
