In this month's Guitar Player magazine there's some coverage of Loopfest - where a bunch of people create complex soundscapes using electonic/computer/etc. delay gear. Never been to one of these, but wouldn't mind checking it out someday...
Anyway, the list of performers this year included "a mandolinist." I wondered if this could've been one of us, but so far a web search for this year's fest hasn't turned up anything. I'll keep looking.
I DID find stuff from previous years' fests, so maybe one of these guys returned this year.  It might have also been the guy discussed in this thread!
Check this page for some shots of Adrian West on Harmony Batwing/eviolin (Audio of Adrian looping here) and on page 7, Hideki Nakanishi (aka Mando Man)! I wish there was audio of him, as he's probably as close to Tekno as I'm going to get! Any guesses as to the maker of Nakanishi's axe?
