At its core, the DC-area acoustic "down home" blues scene was and is rooted in the African American community. A dedicated group of musicians saw it as their mission to carry on their respective Piedmont musical traditions: Mother Scott, Flora Molton, Chief Ellis, Archie Edwards, John Jackson, John Cephas, and foremost Phil Wiggins. Because of their love for the music and willingness to teach, these creators fostered a harmonious environment, mostly centered on Archie Edwards's famous barbershop where Edwards opened his doors every Saturday afternoon for jam sessions.

Sweet Bitter Blues features biographies and supporting essays based on Wiggins's recollections and supplemented by Matheis's research, along with a foreword by noted blues scholar Elijah Wald, historic interviews by Dr. Barry Lee Pearson with John Cephas and Archie Edwards, and previously unpublished and rare photographs. This is the story of an acoustic blues scene that was and is a living tradition.

Phil Wiggins is a blues musician, teacher, artistic director, and recipient of the NEA National Heritage Fellowship (2017), the highest honor the United States bestows on the Traditional Arts. He is a two-time winner of the prestigious WC Handy Blues Foundation Award, in 1984 for Best Traditional Album of the Year and in 1987 as Entertainer of the Year.
