MONROE - Blues singer and musician Mac Arnold, along with his Plate Full O' Blues band, will serve up a heap of blues and soul music to blues enthusiasts at 7:30 p.m. Saturday at the Monroe Arts Center, 1315 11th St. Arnold strums out rhythm and lead on his signature gasoline-can guitars. His high school band, J Floyd and The Shamrocks, were often joined by none other than Georgia native James Brown on piano. After deciding to pursue a professional music career, Arnold joined the Charles Miller group until 1965, when he made the move to Chicago to work with recording artist/saxophonist A.C. Reed.
