Sex Mob's Steven Bernstein had an unusual process for his foray into "radical Jewish culture" for John Zorn's Tzadik label. While researching the music of New Orleans and Cuba, the trumpeter/arranger concluded they had much in common, and then -- as he writes in the liner notes, "Who loves cha-cha and mambo more than Jews?" Placing Jewish secular ("Roumania, Roumania") and religious ("Ani Mamin") themes over New Orleans R&B and Cuban rhythms, backed by a sextet and big band, he's created a seamless synthesis; melodies and rhythms fit together naturally. This is heavy, deliberate music in which the R&B element is most apparent, with raw, funky work by the tenor saxophonists and organist/electric pianist Brian Mitchell. Bernstein's heated solos draw on New Orleans and klezmer sources. True to its title, this is diaspora music, delightfully bridging Willie Bobo's Afro-Cuban boogaloo with Dave Tarras's new-world klezmer might.
