Found via Cafe LA; album review by Rhapsody:

This extensive collection of songs featuring the pioneering female guitarist and blues singer is highlighted by Memphis Minnie's distinctive guitar style and contralto vocals. Minnie sings about committing murder with enough conviction to make you wonder if she wasn't the biggest, baddest bad ass in Chicago in the 1940s.

This is amazing stuff. Check out "When The Levee Breaks" (iTMS URL, RealAudio clip).
