Book excerpt: Alcoholic. Epileptic. Technically challenged. Described as all this and worse, Jimmy Reed nevertheless overcame these roadblocks to become perhaps the most successful R&B/pop crossover artist of the '50s. In "Big Boss Man," musicians, family members, and those whose lives Reed touched offer revealing and heart-wrenching insights into this now-revered bluesman. Although Reed's alcoholism was no secret, its effect on his musicianship is less understood -- this and more is explored in this comprehensive biography of a classic bluesman.
