Merely mentioning a fraction of Bluesfest's line-up should give you an indication of its quality: Creedence's John Fogerty, folk supergroup Crosby, Stills & Nash, disco superstars Earth Wind & Fire, Celtic punks The Pogues, roots rockers John Butler Trio, '70s progressive rockers Yes, blues veteran Buddy Guy, James Brown collaborator Maceo Parker, American guitarist Kenny Wayne Shepherd, blues and gospel singer Jonny Lang, father and son, and musicians both Steve Earle and Justin Townes Earle and many, many more.
