This band, formed in the 1970’s at the Diaspora Yeshiva in Jerusalem, combines American bluegrass, rock and country music with the chassidic nigun. They gained fame after garnering prizes at the Chassidic Music Festival in Israel in the late 1970’s. Today the band consists of eight members and has produced six albums including Melave Malke, At the Gate of Return, The Diaspora Yeshiva Band, and Land of Our Fathers. Samples of their style are available in Real Audio on their website. They sing in both Hebrew and English.
