aka White Trash on Moonshine Mountain
How bad is it? Poor hicksploitation musical comedy/drama with horror elements (bit of a mess).
Should you see it? Only if you're a H.G. Lewis completionist.
Gore pioneer Herschel Gordon Lewis has a 17 disc box set that includes this, an atypical non-gore film of his; the quality of the sound and image are sometimes quite poor and there are missing frames, but there was an attempt to restore what they could. It's the story of a country musician that goes back to North Carolina for inspiration, but runs into a hillbilly family with a still and the revenuers that want to shut them down. Lewis wrote the many songs and they're not bad; it's mostly played as "laugh at the hillbillies" but there are some serious elements (an axe attack, for example) and it just never finds solid ground.
