I'm grateful not only to the film-maker who posted this at youtube.com, but also to the following artists whose samples I remixed:
Ambiencellist Part II by: Claire Fitch,
Music for Modern Listening by: Stargarden
Red-shifted Harmonies by: DAC Crowell
alterstate91-1 by: Brilliant Orange Object
Transmission Drift by: Black Sun Laboratories
cfe.reverse() by: camera.tv.camera
A Rainy Day by: aerosolspray
Combis43 by: MarcoRaaphorst
and the featured artist, Shagrugge, who is part of the title of the piece "Ending the Drought (featuring Shagrugge)".
This kind of creative exchange is why I use Creative Commons licenses, to facilitate people being able to sample or use my work in their projects.
