A Magical Substance Flows Into Me weaves through musical traditions of various communities living in and around Jerusalem. Jumana Manna took as her starting point German-Jewish ethnomusicologist Robert Lachmann’s field recordings of ‘Oriental’ groups in Palestine in the 1930s and his Oriental Music radio series made for the Palestinian Broadcasting Service (1920-1948). In the film we follow Manna as she revisits the communities that Lachmann studied, visiting homes, offices, recording studios, and places of worship.
