Help me ID this Led Zeppelin cover

Here’s a YouTube video showing 25 hours of FedEx flights, set to a bluegrassy cover of Led Zeppelin’s “Going to California” off their 4th album.

I really like that whole Led Zepp album. I really really like this rendition of an awesome song. (And I do like me some good dignified jazz fiddle. Ask me to gush over Anna Schaad sometime.) Does anyone know who performed this piece, and where I can get it?

(Via this funny videos thread.)

Googling brought up a variety (but not an overwhelming selection) of artists.
Going to California cover

There is a whole series of Bluegrass rock tribute albums, called *"Pickin’ on…" *They have two CD’s worth of Zeppelin tunes. “Going to California” is on volume one.
