Genuine legend Taj Mahal lets his gravelly voice pour out the blues on March 25. He plays guitar, piano, banjo and harmonica in genres that simply soaked into the Harlem Renaissance of his youth, ranging from jazz to calypso. He’s played with everyone from Angelique Kidjo and Ziggy Marley to Los Lobos and Ben Harper, serving as both preservationist and visionary. A blues man’s bluesman, he’s as real as they come. Not only does he deliver a good song, he spins a good tale, too.
