After eighty years of ramblin, brer Dickey Betts decided it was leavin time yesterday. Firmly situated in the pantheon of American guitarists, Betts’ melodic, flowing style blended jazz, country, blues, and– self-admittedly– a pinch of Jerry Garcia to build a signature sound that would lead the musical institution known as the Allman Brothers Band for decades following the premature death of his guitar partner, Duane Allman, in its early days. Betts not only carried the guitar load on stage and in the studio, but he also was an accomplished songwriter, responsible for the band’s biggest hit and many of their most familiar songs.
