“The Chemicals Between Us” is a song by alternative band Bush from their third album The Science of Things. It spent five non-consecutive weeks at number one on the U.S. Alternative Songs chart and peaked on the Billboard Hot 100 at number 67 on 4 December 1999. The song closed out the entire alternative rock panel in one week, an unprecedented feat. Many saw this as proof of Bush’s importance to the alternative radio format. It would eventually become Bush’s last major worldwide hit before their 2002 breakup. Songs like “Warm Machine,” “Letting the Cables Sleep,” “The People That We Love” and “Inflatable” would become minor hits, but after “The Chemicals Between Us,” Bush would not score another number one hit until 12 years later with “The Sound of Winter” (2011).
