Can't tell if this is the same guy, but here's a site of a musician who plays the glass harp: GoodWaterMusic.com.

And then there's this entry from Wikipedia which will give you all the history, including facts like George Washington, Marie Antoinette and Mozart were all "Armonica" players, that Ben Franklin invented a spiffy commercial version, and that new music has been composed over the last generation specifically for the instrument. Cool stuff.
