Israeli-American jazz pianist Alon Nechustan and polymath Samuel Torjman Thomas join forces in “Traveling in Pairs,” a musical project that gives a jazz-inflicted treatment to a wide range of Jewish music. Thomas, a professor of ethnomusicology and Jewish studies, is also a multi-instrumentalist, composer, bandleader and singer who is best known for his role as leader of the New York Andalus Ensemble. Nechushtan has forged a name for himself as a genre-buster who remains strongly rooted in jazz.
