John Zorn's absorption of klezmer motifs into avant-garde jazz is remarkable in itself, but even more extraordinary is Masada's utter command of the two genres' fiercely visceral energies. Fueled by Joey Baron's ferocious drumming and Zorn's savage, apocalyptic squeal, Beit is an archetype of focused intensity. (Anyone dying for truth in jazz needs only to hear "Peliyot" to be instantly transfixed and astounded.) Baron and Greg Cohen are among the most powerful and perceptive rhythm sections in any genre, and Dave Douglas, one of the most brilliant trumpeters of his generation, continues to lend immaculate support. Simply stated, this is one of jazz's greatest groups.
