Query: What Happened Here?

I've been a John Mellencamp fan since he went by Johnny Cougar. This CD is such a huge departure from his roots, I don't know where to begin. I was very disappointed! Never in my life have I purchased a CD I wished to return. . . until now. Most songs have a very blue grass/country sound. While this is not necessarily a bad thing, it is here. John Mellencamp is a very talented artist. For the type of music represented, it is not too bad. But for anyone looking for classic Mellencamp, this isn't it.
