Mac Arnold, a well-renowned blues musician and inductee of the South Carolina Entertainment & Music Hall of Fame, will be performing with his band, Plate Full of Blues, at Greer City Park this Saturday. Arnold, who has been playing music since he was 10, is known for his unique gas can guitar, which he made with his brother as a child. After a lifetime of playing blues at home and abroad, Arnold now lives in Pelzer, S.C., and hopes listeners will get a sense of positivity from his show.
