Background: Chester Burton "Chet" Atkins (June 20, 1924 - June 30, 2001), known as "Mr. Guitar" and "The Country Gentleman", was an American musician, occasional vocalist, songwriter, and record producer, who along with Owen Bradley and Bob Ferguson, among others, created the country music style that came to be known as the Nashville sound, which expanded country music's appeal to adult pop music fans. He was primarily known as a guitarist. He also played the mandolin, fiddle, banjo, and ukulele. Atkins's signature picking style was inspired by Merle Travis.
Context: After dropping out of high school in 1942, Atkins landed a job at WNOX-AM radio in Knoxville, where he played fiddle and guitar with the singer Bill Carlisle and the comic Archie Campbell and became a member of the station's Dixieland Swingsters, a small swing instrumental combo. After three years, he moved to WLW-AM in Cincinnati, Ohio, where Merle Travis had formerly worked. After six months, he moved to Raleigh and worked with Johnnie and Jack before heading for Richmond, Virginia, where he performed with Sunshine Sue Workman. Atkins's shy personality worked against him, as did the fact that his sophisticated style led many to doubt he was truly "country". He was fired often, but was soon able to land another job at another radio station on account of his unique playing ability. Atkins and Jethro Burns (of Homer and Jethro) married twin sisters, Leona and Lois Johnson, who sang as Laverne and Fern Johnson, the Johnson Sisters. Leona Atkins outlived her husband by eight years, dying in 2009 at the age of 85. Travelling to Chicago, Atkins auditioned for Red Foley, who was leaving his star position on WLS-AM's National Barn Dance to join the Grand Ole Opry. Atkins made his first appearance at the Opry in 1946 as a member of Foley's band. He also recorded a single for Nashville-based Bullet Records that year. That single, "Guitar Blues", was fairly progressive, including a clarinet solo by the Nashville dance band musician Dutch McMillan, with Owen Bradley on piano. He had a solo spot on the Opry, but when that was cut, Atkins moved on to KWTO in Springfield, Missouri. Despite the support of executive Si Siman, however, he soon was fired for not sounding "country enough".
