Background: Mark Lavon "Levon" Helm (May 26, 1940 - April 19, 2012) was an American musician and actor who achieved fame as the drummer and one of the vocalists for The Band. Helm was known for his deeply soulful, country-accented voice, multi-instrumental ability, and creative drumming style, highlighted on many of the Band's recordings, such as "The Weight", "Up on Cripple Creek", and "The Night They Drove Old Dixie Down". Helm also had a successful career as a film actor, appearing as Loretta Lynn's father in Coal Miner's Daughter, as Chuck Yeager's friend and colleague Captain Jack Ridley in The Right Stuff, and as a Tennessee firearms expert in Shooter. In 1998, Helm was diagnosed with throat cancer, which caused him to lose his singing voice.
Context: Born in Elaine, Arkansas, Helm grew up in Turkey Scratch, a hamlet of Marvell, Arkansas. His parents, Nell and Diamond Helm, were cotton farmers and great lovers of music. They encouraged their children to play and sing at a young age. Young Lavon (as he was christened) began playing the guitar at the age of eight and also played drums during his formative years. He saw Bill Monroe and His Blue Grass Boys at the age of six and decided then to become a musician.  Arkansas in the 1940s and 50s stood at the confluence of a variety of musical styles--blues, country and R&B--that, when merged, later became known as rock and roll. Helm was influenced by all these styles, which he heard on the Grand Ole Opry on radio station WSM and R&B on radio station WLAC in Nashville, Tennessee. He also saw traveling shows such as F.S. Walcott's Rabbit's Foot Minstrels that featured top African-American artists of the time.  Another early influence on Helm was the work of the harmonica player, guitarist and singer Sonny Boy Williamson II, who played blues and early rhythm and blues on the King Biscuit Time radio show on KFFA in Helena and performed regularly in Marvell with blues guitarist Robert Lockwood, Jr. In his 1993 autobiography, This Wheel's on Fire: Levon Helm and the Story of the Band, Helm describes watching Williamson's drummer, James "Peck" Curtis, intently during a live performance in the early 1950s and later imitating this R&B drumming style. Helm established his first band, the Jungle Bush Beaters, while in high school.  Helm also witnessed some of the earliest performances by southern country music, blues and rockabilly artists such as Elvis Presley, Conway Twitty, Bo Diddley and fellow Arkansan Ronnie Hawkins. At age 17, Helm began playing in clubs and bars around Helena.
