<!-- == Origin of the term ''heavy metal''==
The origin of the term ''heavy metal'' in a musical context is uncertain. The phrase has been used for centuries in chemistry and metallurgy, as shown by citations in the ''Oxford English Dictionary''. An early use of the term in modern popular culture was by [[counterculture|countercultural]] writer [[William S. Burroughs]]. His 1962 novel ''[[The Soft Machine]]'' includes a character known as "Uranian Willy, the Heavy Metal Kid." Burroughs' next novel, ''[[Nova Express]]'' (1964), develops the theme, using ''heavy metal'' as a metaphor for addictive drugs: "With their diseases and orgasm drugs and their sexless parasite life forms—Heavy Metal People of Uranus wrapped in cool blue mist of vaporized bank notes—And The Insect People of Minraud with metal music."<ref>[[William S.
