Frozen Warnings

Frozen Warnings is the seventh track of The Marble Index, 4:02 long. Nico sings over her harmonium with John Cale's viola and arrangement. Julian Cope calls it the most beautiful song she ever recorded and hears it as autobiographical, with railroad imagery, a meditation influenced by Cage, a rural drone, echoes of Henry Flynt. NME's 2005 reissue review found the harmonium and her diffident singing especially effective here. No interview or liner note explaining its meaning was found.

She recorded it for John Peel's Top Gear on February 2, 1971, with No One Is There, Janitor of Lunacy and Secret Side, harmonium and voice only; it was issued on Strange Fruit in 1988 and on the 2016 Gearbox release Nico 1971: The BBC Session. John Cale sang it to open the tribute concert Life Along the Borderline at the Royal Festival Hall in London on October 11, 2008.
