954 - King Crimson 21st Century Schizoid Man 1969

King Crimson’s music drew on a wide range of influences provided by all five group members, including Jimi Hendrix, romantic- and modernist-era classical music, folk, jazz, military music (partially inspired by McDonald’s stint as an army musician), ambient improvisation, Victoriana and British pop.
Their debut album "In the Court of Crimson King" starts off with the fiery "21st Century Schizoid Man," a mix of scathing proto-metal and fiery jazz.
