The title of this suite of collages is taken from a work by composer Philip Glass, 1000 Airplanes on the Roof http://www.youtube.com/watch?v=5fz4lgZgmsw|
'What Time is Grey' (Track 6 of the CD) is relentless repetitive, strangely mysterious and curiously predictable.
1000 Airplanes on the Roof is a melodrama in one act by Philip Glass which featured text by David Henry Hwang and projections by Jerome Sirlin. It is described by Glass as "a science fiction music drama".
The work was commissioned by the Donau Festival, Krems an der Donau, The American Music Theater Festival, Philadelphia, and West Berlin City Council in 1988. The opera premiered on July 15, 1988, at the Vienna Airport in Hangar #3. The performance featured vocals by Linda Ronstadt and was conducted by Michael Riesman.
