As their name implies, The Delta Generators combine the urgency and soulfulness of delta blues with the power and energy of early rock ‘n’ roll. While, in the broader sense, they could be classified as a blues band, there is room on that big blue canvas for brush strokes of Memphis soul, Louisiana funk, and classic rock ‘n’ roll. The combination of clever songwriting and inspired performances on their new CD “Devil in the Rhythm” shows why critics and audiences are calling them the best new blues band in New England.
