3/5 - I needed to hear maybe 5 songs of this album, but certainly not 2 hours. This is like when someone suggests The Count of Monte Cristo for your bookclub. You've got an epic assignment of 1200 pages of classic material to consume, and you've more or less got the gist 1/5 of the way in, because it's all more of the same. There's not going to be any surprises on side B of this monster.
This is a documentary-worthy piece of work that is important for all sorts of reasons, I'm sure. It belongs on this list. I'll give it a 3 because if I'm in the unlikely mood for some bluegrass, now I know where to go. That said, it can't go any higher because: a) It's more of a catalog than an artistic statement as an album and b) I hate skits on country/bluegrass albums as much as I do on hip-hop albums. Just play the song; isn't the album already long enough?
