Mark Stoffel is the mandolinist with Chris Jones & the Night Drivers. A new solo album just out,
Coffee and Cake includes this international assembly of mandolinists doing Glenn Miller's In the Mood.

You'll see many names you recognize.
My two surprises were the absence of Chris Thile and the presence of Chris Luquette who's known mainly for his guitar work.
