Edmonds Jansons’ film Choir Tour gets by on one key insight: a group of children may seem like a set of solid objects, but it acts more like a liquid. In his 2012 short, a childrens’ choir runs amok through an airport and a hotel. It’s not that they’re intentionally causing trouble, but like a ball of mercury, they clump together and flow from one space to the next, without any regard for rules or reason.

Jansons shows this all with a minimal, highly compressed style, which was probably the only way to go–you need a certain amount of abstraction to make this particular image work. Credit, too, to the impressive sound design from Girts Biss. It isn’t easy to walk the line between irritating and charming, but the singing in Choir Tour pulls it off perfectly.
