Information on Satie as a precursor of Modernism may be obtained by contacting Daniel Harding, who wrote his Masters' thesis on this topic at the University of York. Daniel may be contacted through the author of this site. Some information may also be found in the archives of Niclas Fogwall's Satie site mailing list.
Daniel & I are working to put a summary article of his Satie & Modernism work online on this site. This should be online sometime in 2008.
