Query: Bluegrass both modern and traditional

I first encountered the Meat Purveyors through the song "Thinking About Drinking" (from the album All Relationships Are Doomed To Fail), yet decided to explore them first through this album, not able to pass up a bluegrass album with a Talking Heads reference in the title. I was surprised to find that, by my standards (at least), the Meat Purveyors are very much rooted in traditional bluegrass. Some purists might object to some of the stuff here, but the hauting "Travel & Toil" and "Morning After" show a real mastery of the genre. Not that they'll let themselves be forced into a corner; their cover of "We Kill Evil," a punk tune which sounds, in the Meat Purveyor's talented hands, as much a gospel number as left-wing manifesto, ends the album on a delighfully surreal note. Not every song works, but there is a lot to like here.
