Country players get slagged off a great deal. And that's why playing like this exists: to refute the folks who don't know what they're talking about. It might just be a clip, but there's more dexterity here than in any pop song on the radio.
I'm pretty foggy on the comings and goings of Dillard family members throughout the various line ups. And this song might not be the greatest representation of what the group's known for, so listen with that in mind.
