Music was always a family affair for Bobbie Nelson -- she grew up playing music with her younger brother, Willie Nelson, and played piano with his band the Family for over 40 years, adding a strong melodic undercurrent that became one of the trademarks of Willie's music. Bobbie's keyboard work, informed by gospel and hard country as well as piano jazz and traditional pop, added a buoyant touch that boosted the versatility of Willie's musical outlook. Bobbie was an accompanist who rarely stepped into the spotlight, but 2007's Audiobiography was a solo LP where she showed off the full range of her influences, and 2014's Farther Along: The Gospel Collection and December Day: Willie's Stash, Vol. 1 were amiable collaborations with her brother, playing favorites from throughout their lives. 2023's Loving You gave a posthumous release to a collaborative project between Nelson and violinist and songwriter Amanda Shires.
