Thom Yorke scores 18-day soundtrack for Stanley Donwood Exhibition

The ambient piece - entitled "Subterranea" - features samples from "Fitter, Happier" (as reported by Triple J), and despite its extensive length, no two minutes are the same.

"Subterranea" backs Stanley Donwood's The Panic Office showcase in Sydney. The exhibition looks back on the artists work from the past 25 years.

The Stanley Donwood exhibition runs until 6 June at Carriageworks, Sydney.
