Some nice theme work there, Maggie. The web page piece had an intro that sounded familiar...I think I may have used the same Yamaha intro, or a very near variation of it, on a song my partner and I recorded for a contest several years ago! :-)
You and I seem to share some similar tastes in music, particularly with Larry Fast's work. Man, that guy did some killer synth albums. His rendition of "Slaughter on Tenth Avenue" from the first Synergy album is still my overall favorite piece of synth music, although it has to compete in my head with the entirety of Tomita's "Snowflakes are Dancing" album. I'm also a Zappa fan (Frank was one of the first and most innovative users of the Synclavier, the forerunner of all current computer based digital synthesis).
The people you cite are *not* strange bedfellows. The common thread running through all of their music (with the possible exception of John Tesh...sorry!) is a creative and original use of synthesis in their music. Two or three synth notes from any of these people's albums, and you know who and what you are listening to.
Lots of people use synthesis, but only a handful have done truly creative, and more importantly, *musical* work with them. Like Pete Townshend, for example. Anyone heard any more on his kiddie porn situation?
