With respect, I think you're mixing "blues" and "bluegrass". The latter is "white" music, usually stemming from the Scotch-Irish in the Appalachian Mountains. The blues were originally "black" music from New Orleans and the Mississippi Delta. Obviously, all these styles are mixed today, but to my ear anyway, HADESTOWN wants to be a blues musical.
As someone said above, COME FROM AWAY is contemporary Celtic rock.
