Heather Waters posted this to her FaceBook: Michael Jackson's Billie Jean - Performed by Casey Driessen (Edit Version)
As he describes: Solo looped fiddles recorded and stacked live before your very eyes and ears (to a click track). While teaching at Mark O'Connor's Fiddle Camp, we got the word that MJ was gone (yes, even at fiddle camp). I worked up this version to pay tribute to MJ in my concert the following night.
I guess Heather kinows Casey, and I'll have to learn more about him, he's very talented.
