Willie Nelson and his sister Bobbie Nelson will release Farther Along: A Gospel Collection on Aug. 10. The album features tracks from the duo's 1996 out-of-print album How Great Thou Art and newly-recorded material. As children, the siblings were encouraged by their grandparents, who raised them, to sing and play music in church. "Gospel music is how I learned to play the piano," said Bobbie. "The gospel songs on this record are the songs that Willie and I first started playing as children. That is what makes this the most special record I have ever done."
