Rather than have the whole band play throughout, smaller combinations could have been used. Banjo and guitar for one section. Banjo guitar and fiddle for another. Maybe a solo by the instrumentalists, (not all at once).

There was for my taste a conflict in styles. The Irish approach doesn't always work with the Appalachian sounds particularly if they are combined in a heavy beat. It mashes everything together in a plod.

Big is not necessarily better.
