When Matisyahu emerged in 2004 with his debut album, Shake Off the Dust...Arise, his musical persona seemed to some a novelty. Here was a Hasidic Jew -- dressed in a black suit with a broad-brimmed black hat worn over a yarmulke, and sporting a full, untrimmed beard -- who nevertheless performed toasting raps about the glories of traditional Judaism over reggae beats in a dancehall style directly from Jamaica. Moreover, he punctuated his performances with stage diving. It may have seemed like a joke at first, but Matisyahu was serious about his craft, and his diverse style soon garnered Grammy nominations, gold record certifications, and a broad audience.
