Trommy?

If you want to hear a twelve-minute rock opera based on Tron, a bluegrass medley of Radiohead hits, or an all-melodica version of Spybreak, get thee to this site.

It would appear that Brendan Small, of the brilliant Cartoon Network series Home Movies, was involved in at least some of these projects, but mostly it was some dude named Chris Hardwick. Thanks to Lesley T., best P.A. ever, for the pointer.
