Since their emergence, the Klezmatics, often called a “Jewish roots band,” have led a popular revival of this ages-old, nearly forgotten art form that, in its first incarnations, flourished at Jewish weddings and other joyous occasions. They have performed in more than 20 countries and released 11 albums to date—most recently the album Apikorsim (Heretics), produced by Danny Blume (who helped the band win a Grammy in 2006) and the first of the band’s albums to feature only the 6 members. They have also recently served as the subject of a feature-length documentary film, The Klezmatics: On Holy Ground.
