This set bridges the gap historically and musicly for Emmylou Harris from 1969 very first studio album Gliding Bird to her 1975 2nd studio album Pieces of the Sky. I consider it an essential addition to my Emmylou CD collection. It's a very nice set to have for this reason alone.
That said, Gram Parsons was a great singer/songwriter and you get his albums Grievous Angel on one CD and GP on another. There are alternate versions of songs and interviews to enjoy. A great set that is out of print.
A lot of people never caught on to Gram Parsons. He introduced country music to Emmy Lou Harris.
He was an early country rock singer/songwriter/musician. Some great cuts on this album.
