This tricky musical documentary captures the director’s search for an idea of the proper soundtrack for his film. With a handful of diverse musicians, composers, producers and critics featured, the work effectively becomes an understated ode to Lithuania’s newly burgeoning music scene. Yet there is also a catch: the very abundance of options makes it nearly impossible to choose one, so the only actual soundtrack can be the documented soundscape of the search itself. The director is left standing on the “naked shore” mentioned in one of the songs, obsessively gathering pebbles and seemingly having lost a sense of direction.
