music bluegrass

What is the relationship with the word "crow" and bluegrass music?

Old Crowe Medicine Show and hundreds of other bands with the word Crow in it-Steve Martin's new album is called "The Crow …" Let me be clear, bluegrass bands have the word crow in it. So a lot of bluegrass songs, there an historical aspect of it?

The only thing I could think was ok JD Crowe progressive bluegrass banjo player
