With a wall of soul sound that could tumble Jericho, these four powerful women singers stand at the front of the stage and make believers of every audience member. Rocking, scolding, testifying and torching, the Blues Broads are legendary singers Tracy Nelson (Mother Earth), Annie Sampson (Stoneground), Dorothy Morrison (Edwin Hawkins Singers) and Angela Strehli. Each one of them have had successful careers and led their own bands for decades. Nelson wrote her classic “Down So Low” which has been covered by Linda Ronstadt, Etta James, Maria Muldaur and Cyndi Lauper. Her new CD, Victim of the Blues is nominated for two 2012 Blues Music Awards. Morrison is the Grammy-winning lead singer of “O, Happy Day,” the only traditional gospel song ever to cross over and become a bone fide pop hit. Sampson starred in the long –running production of “Hair” and has recorded with Elvin Bishop, Taj Mahal, Buddy Miles, Maria Muldaur, Eddie Money and Country Joe MacDonald. The “Queen of Texas Blues,” Strehli worked with Stevie Ray Vaughan and every other Austin and Chicago blues player of note through her decades of guiding work with Antone’s –both the famous club and the record label. Now, as a vocal team with an all-star Bay Area band, these four women are having some of the most fun of their lives.
