Jews love familiar melodies, even after they grow mouldy. We get stuck and resist being open to different approaches that can sometimes move us forward. Jewish music is merely a ‘cover’, a ‘midrash’ on a Jewish text. New music creates new mould on our sacred textual ‘host’. Hopefully, the new musical midrash interprets the text, creates understanding, inspires deeper meaning. Sometimes, the new mould smells badly. Sometimes it is remarkable. But we need to be open to the new, lest our musical interpretations of our tradition become stale and rotten.
