Disintegration Loop 1.1.

11 September 2001. Composer William Basinski is due to attend a job interview in Lower Manhattan, at the World Trade Center, but decides not to go. Moments later, the Twin Towers collapse. From his Brooklyn rooftop, Basinski films the final hour of daylight as smoke fills the sky and dissolves into dusk.

The Disintegration Loops is a landmark of hauntological music. The four-part cycle originated when Basinski digitised ageing 1980s analogue tape loops that began to physically disintegrate during playback. Paired with his footage, the work became an elegy to the victims of 9/11.
