Charles Alfred Leavell (born April 28, 1952) is an American musician. A member of the Allman Brothers Band throughout their commercial zenith in the 1970s…he has served as the principal touring keyboardist and de facto musical director of The Rolling Stones since 1982.
In addition to his musical career, Leavell is a tree farmer…an occupation that began when his wife, Rose Lane Leavell, inherited land in the early 1980s. Together they created Charlane Plantation, now a 2500-acre award-winning Tree Farm and hunting preserve. The Leavells are two-time Georgia Tree Farmers of the Year, and were selected as National Outstanding Tree Farmers of the Year in 1999. They are staunch supporters of sustainable forestry, conservation and environmental protection. Chuck wrote his first book, Forever Green: The History and Hope of The American Forest in 2000. His autobiography, Between Rock and a Home Place was published in 2005, and is acclaimed as one of the best rock autobiographies ever published. In 2006, Leavell wrote a children’s book, The Tree Farmer. His most recent book is Growing A Better America: Smart, Strong, Sustainable (2011, with J. Marshall Craig), the theme of which is “smart” growth. It has been called one of the best “common sense environmental books of all time”.
